When I want to plot a certain function,  namely gevrlevelPlot( ), I also get output like min v  max that I want to supress. I only want to keep the plot but I can also not just externalize the plot. So is there a way for me to supress some of the results, but not all of them?>

Hi.

I have a discrepancy (bad rounding) between console and report (even when 'asis' is set):

<>=
library(quantmod)
getSymbols("GS")
last(GS$GS.Close['2012-04']) #displays 115.15 in console and 115.2 in pdf
<>
 #sorry, I couldn't use the at sign as it's again and again changed to the name of one of the below commenters.

My output goes past the right margin and up to the edge of the page before wrapping around. How can I get the output to stop at the right margin?

My R output is quite long (stepwise regression) and I'd like to either make it smaller or crop it so it fits on the same page. How can that be done?
Thanks for your help,
Tal

Yihui, 

The output from my R functions are overflowing past the right edge of the shaded area--even past the width of the page.  I've tried reducing the width in options setup, which, for some reason, does not seem to change the output printed by the R package's function.

My setup chunk is as follows:

<<setup, include="FALSE," cache="FALSE">>=opts_chunk$set(fig.path='figure/minimal-', fig.align='center', fig.show='hold')options(width = 90)

I'm using  <<tidy =="" true="">>= in the code chunk.

See pdfLaTeX screen here: http://goo.gl/NRtyn

Thank you for your help.

Hello,

I'm having a bit of an issue using options eval=FALSE and echo=(a numeric vector) in an Rmd file.

The following produces an html file that returns just the first line (summary(cars)), and the output from all three, as expected:

summary(cars)  
str(cars)  
head(cars)  

However, if I change it to:

summary(cars)  
str(cars)  
head(cars)  

then all three lines show in the html file, while I would expect only the first line. I'm not sure if this is a bug, or if eval=FALSE then the script is not parsed into different expressions so that it reads the entire chunk as one expression... or if I'm missing something else...

It probably seems odd that I would want to do something like that, but I have a script which I am using in two different Rmd files. In each Rmd file I load the script using read_chunk, and in one Rmd file I need to execute the entire chunk (but hide some irrelevant code), while in the other Rmd file I want to hide the same bit of the chunk but not execute the chunk.

Hi Yihui,

I really appreciate knitr. Just one question:
What is actually the main reason, why long lines of text ouput are sometimes still too width, although options(width=60)?

I have tried all other solutions with listings etc., but from my point of view the default setting of knitr is the most beautiful and convenient one.

Do you think this is going to be solved by R soon? How can I contribute to find a solution for this problem?

Thanks in advance for an answer.

Hi,

the following chunk fails despite error=TRUE, i.e. knitr ends with an error instead of printing the chunk error message:

x<-rnorm(1)

if(x>=0)  
print("x größer oder gleich 0")  
else  
print("x kleiner als 0")  

Is there a different option that allows me to just output R errors? Is it a bug?

Thx
Stefan

This page describes how to have inline output of the results of R commands. But is it also possible to have inline chunks containing the formatted R code, similar to what chunk output does with the echo=TRUE, eval=FALSE option?
