Can you help me?  I have put together several files to create a single file with a three-dimensional array.  Now I just want to create some basic plots.  My challenge that I am having problems with is this:
I need to graph all of the values in one dimension that have a certain value from another dimension.  There are neither dimension titles nor column titles and I'm not sure how to reference my data in order to properly graph it.

Hello! I am very impressed by your fantastic job! Well done and thank you for helping the community.
I have difficulties in using lyx and R codes: Particularly, I am using codes from packages installed. Unfortunately, when I run the pdf, lyx shows me the error. ALso R do not read the function (only R-studio does!!!). I would be very happy if you are gonna help me. In case, I can give u my e-mail to have a better communication. Thanks in advance and keep it up!

Let me start by congratulating you on knitr.  I am a long-time Sweave, cacheSweave, RweaveHTML and pgfSweave user and I really appreciate your efforts to address the few issues with these packages.  In preparation for writing the 2nd edition of my book (Biolostatistical Design and Analysis using R), I am considering migrating fully to knitr.  The book is published by Wiley and therefore I have a style file that provides a highly customised look etc.

I am having a few issues getting knitr to work neatly with xtable to produce tables.  I have tried using the results='asia' or results='tex', yet the tables always seem to end up between knitrout, kframe tags.  I have included a snipped below to illustrate.

begin{table}[htbp]caption{Bla Bla Bla}label{tab:BlaBla1} begin{tabularx}{linewidth}{cc}   hline   A&B   hline<<tab1, echo="FALSE," resuls="asis">>=tab <- expand.grid(a=1:4,b=c('A','B'))library(xtable)print(xtable(tab), include.rownames=F,floating=F,only.contents=T,include.colnames=F,sanitize.text.function=function(x) x, sanitize.rownames.function=function(x) x)@    hline end{tabularx}end{table}

The above is a somewhat simplistic example (in that the desired result could just about be obtained by using more arguments to the print.xtable() function.  However, it mimics the issue I am having with the modified tabular environment that I must honour for the publisher.

In order for the chunk to play nicely with the tabular environment, it must not itself be within a framed environment.

I have had a look through some of the hooks and they seem to indicate that when results='asis', the result should not be placed within knitrout and kframe environments, yet they clearly are.  Is there something obvious I have missed.

Essentially, I want to be able to process a chunk and have it appear without any environments.  If this must be done by redefining one or more hooks, I would really appreciate some pointers..

I seems somewhat analogous to the issue with asis plotting and the use of fig.cap etc.

Regards and thanks again

I am not sure where to take this idea, so I'll leave it here.  I do data analysis and write academic papers; mostly I collaborate with Word users, but I use LibreOffice, and use Zotero(zotero.org) to handle bibliographies, research notes, citation formats, etc.  Of course, I use R/RStudio for data handling.

But, my workflow is broken up.  The knitr/R/Rstudio side doesn't play nicely with the libreoffice/zotero side of things, and what I'd love is one workflow where I could switch seamlessly between the data analysis and the writing tools.  odfWeave did some/most of this, but without the elegant interactivity of Rstudio/knitR.  I am loath to give up Zotero, but it make use of all sorts of hidden codes in LibreOffice to do its magic, so it doesn't play nicely with plain text tools like Emacs, etc.

I can't imagine I'm alone in this set of tools, nor in wanting to enhance my workflow.  I'd welcome any ideas you had on how knitR/Rstudio and LibreOffice/ZOtero might play together nicely.

Thanks for a great tools!

Yihui,
  It was nice meeting you at Nashville and I thoroughly enjoyed your talks. I have a question regarding interactive graphs. I run reports for a govt. agency and would like to generate interactive figures for them using googleVis and knitr. However, they are apprehensive about posting these files as html and moreover, they would like a pdf file since it can be saved and does not require an internet connection to view. Is it possible to embed the interactive html figure into the pdf file? Since they would like to print this out and distribute, it would also be great if these figures could be split up automatically into multiple pages when printing. Is this wishful thinking or can this be done using knitR?

Thanks.

Hi,
first of all congrats on knitr. Second my apologies if this is not the right place, but as far as I could see on your knitr page comments are closed.

Here is my quesiton. When running knitr for Latex output it converts dots etc. in _ and unfortunately this is causing me headache. As I am try to create with my package a pdf using a function (which is using knitr) in the tempdirectory of R. I have to use the temporary directory due to R policies. This leads to the situation that sometimes when the Rtempfiles has unsuitable characters, they get replaced and then my function breaks down. Is there a way to switch this feature off when knitr is used? Any help is appreciated. I am happy to send you the package (an older version is already on CRAN PopGenReport), but the newer version is much more stable an I am submitting it today (without the vignette because I cannot build it due to the issue mentioned above).
THanks in advance

Hi Yihui

As a fifth year Ph.D student in statistics, seems you don't have any research and papers in pure and applied statistics. You spend all your time on coding and R. Is this a reasonable choice or wasting time? Coding and R are just tools for statistics but not statistics.

Hello Yihui,
Hope you are doing very well recently. First, I Iike to commend your efforts in developing literate programming especially in Statistics. All your R packages have been very helpful and knowledge contributing, especially the knit r. They are all eye openers. I got to know about R markdown, pan doc and a statistical graphics animation through your works. I have also known Tal Galili earlier through his quality R blogs. Both of you are currently my role models and and distant academic advisors in literate programming. I have now learned writing in Latex using Tex Studio but Statistical animation and graphics is my current interest for my data mining PhD. work. I present what I like you to help me with as soon as possible in what follows:

1. My current University requires that I have one year training abroad during my Ph.D. research. Can I come and train under you?
2. Buying your knit r book online has been a problem. Please advise.

Hi . The reason i am commenting is because i am frustated by my approach about R markdown figure captions. Whenever i create a figure i i set fig.cap="my figure caption" but the figure that is generated does not show the caption. I want something simple like "Figure 1: my figure caption". i saw an example of a report made by a person a he used R markdown to generate the figure caption using fig.cap but so far i have been unable to add it.

Guest *Prof Jose Iparraguirre* @ 2015-04-09 16:02:54 originally posted:

Hi Yihui,

I'm starting off with knitr (just got your book).

So far, the examples are working fine within RStudio but not within Texstudio.

I've also read that Lyx may not have all the Latex bits and pieces implemented and that reading a fairly complex .tex document in Lyx is not that straightforward. You see, I've been writing a book for some months now and have written over 100 pages already, and since I've discovered knitr I don't want any longer to create charts in R as png files and ask Latex to read them as figures, etc. Your package is the way forward!

However, TexStudio is my editor of choice and somehow using RStudio just to add a figure here or there in a document is not what I have in mind. I prefer to use Texstudio.

The problem I'm finding has been reported elsewhere but I still can't get around to solving it: it's the rather familiar "Could not start Build & View:PdfLatex" error message within Textstudio when I try to compile a .Rnw file (even the simplest of examples).

I've downloaded everything again (Rstudio, Mitex/Latex, TexStudio, the latest version of R and of the R packages including knitr), and in the TexStudio configuration window I have for PdfLatex this: "C:/Program Files/MiKTeX 2.9/miktex/bin/pdflatex.exe" -synctex=1 -interaction=nonstopmode %.tex
and in the Build window in the User Commands have knitr:knitr and then Rscript -e "library(knitr); knitr(knit2pdf('%.Rnw')"

I've also checked the environmental variables and R is included in the path.

It'd be a pity if I can't keep working with Texstudio, but there's no way back when it comes to use an output generated in R within the document now that I've come across knitr.

Any help, greatly appreciated.

Guest *Shicheng Guo* @ 2015-08-02 07:14:57 originally posted:

Hi Yihui,

Is there any suggestion on how to prepare figures in then publishing of papers. Here is my confusion. As you know, In order to publish a paper (genomics and bioinformatics), we need spend 4 or 6 month and prepare about 6 figures. For each figure, it will include 4 or 6 sub-figures, such as Figure 1a, 1b, 1c...

Acutally, for each sub-figure, they are created by R or Rstudio independently. And then we will ensemble them into a complete Figure 1. But in this process, some figures need to be re-built since the font maybe too small or some other reasons. Do you have any suggestion or great strategy: how to prepare the figures and publish them with high efficiency and avoid to re-built again and agian?

I have a small post to this question in biostars. but I am not sure I interpret this problem clearly.

Really hope to get some suggestion from you.

Hi Yihui,

Proud to say that I found your Dynamic Documents text because of Dr. Maitra at ISU. Thank you so much for the minimal example in there - it helps so much.

Anyway, I have a question for you here. So I tried to copy your minimum example (p. 13, 2nd ed) and it works fine, except for some reason, the data points are not appearing. Here is how I typed the code in the .rnw file:

documentclass{article}
begin{document}
title{A Minimal Example}
author{Yihui Xie}
maketitle

We examine the relationship between speed and stopping distance using a linear regression model: $Y = beta_0 + beta_1 x + epsilon$.

<<model, fig.width="4," fig.height="3,fig.align='center'">>=
par(mar = c(4, 4, 1, 1), mgp = c(2, 1, 0), cex = 0.8)
plot(cars, pch = 20, col = 'darkgray')
fit <- lm(dist ~ speed, data = cars)
abline(fit, lwd = 2)
@

The slope of a simple linear regression is Sexpr{coef(fit)[2]}.
end{document}

then I asked R to turn it into a .tex file using knitr, and everything works fine, except the plot(cars, pch=20, col = 'darkgray') line. I tried copying and pasting this line into R; the gray points appear. But they don't appear in the .tex file. Am I missing something?

Thank you!

Hi Yihui,

Just read your blog about "Ghost printing". I'm trying to print out a "flextable"/"regulartable" using knitting a html in Rmarkdown. I tried to put "(mytable)" around my function. It's still not printing. If I use "print(mytable)", the nice format in mytable is lost. Do you have any suggestions on that?

Thanks a lot!

hello Yihui,
I have a small question when knitting rmarkdown.
rmarkdown shows error on this code line: a <- read_excel("path",sheet="sheet1",range=a1:c9"), saying "Error in FUN(left,right):non-numeric argument to binary operator calls:...ops.data.table->NextMethod->ops.data.frame->eval". However when running the trunk separately it will not generate error. any idea? thanks in advance

Hi Yihui,
I've been searching and searching online for an answer to the following question but haven't found any, at least none that works.
Can you read an rtf file into Rstudio/R-Markdown?
I want to create a document using one or more external documents as well as markdown code.
Greatly appreciate any help!

Hi Yihui,

I figured you might be the best person to ask about knitr-ing R Markdown that uses both Western and Simplified Chinese characters. There seem to be periodic postings indicating how to do this with ctex.sty and xeCJK when using XeTeX, but I am not able to get any of the solutions to work. There must be a straightforward way to do this. Any suggestions, or a pointer to a web page would be appreciated. I would love to be able to handle this completely through the YAML header.

Thank you for creating blogdown! Am trying to mimic MKDocs with both the site two level outline theme and a local editor with three levels to allow separate projects like Typora but to include auto publishing. Reading your book blogdown: Creating Websites with R Markdown.

Hi Yihui,
Some portions of your wonderful book BookDown.org & RMarkDown.RStudio.com/ need modifications. I am reading and reading and reading and adapting the portions that are left out. If interested in what I am experiencing as what is left out, please reply and I can share exactly what should be inserted in your wonderful book.

Guest *Andrew* @ 2019-03-22 09:55:14 originally posted:

Just seen your book on creating websites using blogdown.
Firstly, thanks for putting this on line.
Secondly, I would like to suggest a reflection on the wording used here (https://bookdown.org/yihui/blogdown/a-quick-example.html) footnote 3: with mental health being an increasing issue among students and young people, I wonder if a different phrasing to express your frustration with _index.md might be more appropriate?
All the best

I just watched your webinar about HTML and Leaflet with Java script you provided many months ago. I don't know how to show the sum of clustered groups (using markercluster) on Map. And when I have more than 1 million records, the RStudio crashes on me with Markercluster feature on.

Hey Yihui,

Thanks for rmarkdown, it really helps when I need to write a report. Now I am switching to Jupyter notebook and really missed the kable function from knitr. Any plans to create some equivalent stuff for python?

Hi Yihui, can we run multiple SQL statements in a SQL chunk in R markdown? For example,

create table table1 as select * from table2;  
select count(*) as cnt from table1;  

Right now, it errors out and says "one query is expected".
Thanks!

When I run "create table" in a sql chunk, it returns error. It seems that it errors out if nothing is returned. Can we change it.

When I Knit the chunk, the results can show in rmarkdown but can't show in output files. Can you tell me why?

Hi Yihui,
When I use Lua filters to change the text color in blogdown, the change works well after rmarkdown::render(), but the changes can't show up after blogdown::hugo_build() and blogdown:::serve_site(). Can you please tell me why?
output:

Yihui,
thank you for rmarkdown and many many authoring tools.
To make medical research papers, I'm using ztable package which has some good features like highlighting table and table statistics, however, it is not supported by rmarkdown.
Making Latex code into txt file and inserting in the rmd is one of the solutions, but I wish I can use ztable function inside code chunk like kable function.
Please consider universal method knitting automatically generated
Latex codes inside the code chunk.
I found that many other users have same issues, but I can't find answers.
Best solution was inserting with input {generated latex txt}

With best,

I've been trying to read your book "Bookdown" for some time. Quite frankly, it is a hard read. I'm trying to follow the mechanics of bookdown, and it is a tad confusing! Just to do a simple book is proving quite a chore; I like to see some sort of order in the files needed to create a book, like yaml files before or after rmd files and are there any other strange files I need to add (not images or text files).
