Thank you for this great package. I have a quick question. I have output from a .Rnw file that has the R code and output color coded. I need to remove the color coding and I applied the "highlight=FALSE" option. This turned off the color coding, but it somehow also changes the spacing in the output in a random way: sometimes, the spacing is there; other times, the spacing disappears between the output and the code. Is there a way to turn-off color coding but keep the spacing?

Hi I was wondering if you have ever had .gif in knitr which would be compiled into a pdf with an animated gif. Is that even something possible?

Dear Yihui Xie,

is it also possible to use knitr in Atom or maybe Jupyter Notebooks? Would be awesome if it comes for Atom. Because I have a perfect workflow in Atom for my type of work but to knit documents I find myself opening Rstudio just for that....

Thanks so much for your awesome work. This is ... amazing.

Greetings,
While using Bookdown, Is it possible to generate a very large plot (for example: 10 inches wide X 7.5 inches high) then have it displayed portrait (rotate 90 degrees) style on a page?
Thanks

Hello,

Great Articles I have learned so much about both knitr & Sweave!

I have an issue with my code right now that is using LaTeX & Sweave at the same time.
I have a main file that takes in 6 other files using SweaveInput{}.

The only problem is every time I go to execute it, the output states:

Execution haulted.
All connections are in use.

I have tried to close the connections using CloseAllConnections(), but this also throws a different error. I am at the end of my rope, I am not sure where to go from here. PLEASE HELP!

Thank you,
-Dante

The output in my html or even pdf after i have knitted or rendered is very different compared to the outputs in my R markdown before knitting. Someone help me to solve this situation.

Dear Sir,
How to resolve the following errors when compiling R Notebook into a document?
All the required packages are successfully loaded, still the issue persists. Kindly help ASAP.

CODE:

# pipe operator
x<-5:15
mean(x)
x%>%mean

sum(z,na.rm=TRUE)
z%>%sum(na.rm=TRUE)

sum(is.na(z))
z%>%is.na%>%sum

mean(is.na(z))
z%>%is.na%>%mean

OUTPUT:

|...................................                 |  67% (unnamed-chunk-1)
