[Tex/LaTex] How tontegrate R code in TeXStudio

rrstudio

I am writing my thesis in TeXStudio. One chapter features plots / analysis etc. that I am writing in a markdown in RStudio.

Is there a way to kinda "link" the documents so the output from R is displayed in my TeXStudio document and updated automatically in case I change my code in R?

best wishes (:

If I understood you correctly, you just have to save the plots as pictures (.png, .jpg etc.) in your LaTeX figures folder and open them as usual. You can also specify in LaTeX any other folder on your computer by giving the full path.

\begin{figure}[htbp]
\centering
\includegraphics[width=0.5\textwidth]{F:/User/Thesis/R_Project/figures/example.PNG}
\caption[Title of Figure]{Actual Caption. It's nice if you understand the fig. by just reading this caption.}
\label{fig:res_r_lable}
\end{figure}

[Tex/LaTex] How use LaTeX counters to label knitr code chunks

That is a challenging problem. As Ben Bolker pointed out, it is a one-way flow: when R is done, nothing will come back from LaTeX to R again, so R will not be able to know the value of \ref{SetSeed} in LaTeX.

However, I do not think it is completely impossible, because you actually have the *.aux file generated from LaTeX, which you can parse with R for the solution numbers, and update the raw R script from purl() with this information. One approach is that you use the same label for the R chunk as you used for the Example environment, and you will get a code chunk in the output like:

## @knitr SetSeed
# R code

Hopefully you will also see this in the *.aux file after you have run LaTeX on the *.tex file:

\newlabel{SetSeed}{{1}{1}}

Then you replace SetSeed in the R code with Solution 1.1. In all, you need some post-processing of the R script.

[Tex/LaTex] knitr in RStudio produces ‘Undefined control sequence’, alongside other issues

The compile sequence for a file using LaTeX and R code which is to be processed through knitr is as follows where * is your filename without extension. I would recommend that you run these using TeXworks (bundled with MikTeX) and R before you diagnose the problem in RStudio. RStudio in the past was very picky on setup of supporting programs (I have not used it recently)

The *.tex file is renamed with the suffix *.Rnw (this is case sensitive)
Within the now *.Rnw file you need to use R-blocks to load any needed R library's and do any computations.
When the *.Rnw file is ready for a compile (and you file is ready when renamed) you then need to start R, change the working directory to the same one as the *.Rnw file. Now you need to Load the knitr package. (If needed install it and thereafter just load it.
In the R console you issue the command knit *.Rnw and this will create a *.tex file with the R commands replaces with the output.
Now return to your LaTeX and run pdflatex twice and then run your viewer.

If you are using an IDE there are setups which allow you to do all of this from within the LaTeX IDE. However I am not familiar with current version of RStudio. In the past it was not able to run knitr from RStudio as then RStudio was hardwired for Sweave.

I would recommend you visit http://yihui.name/knitr/ as the author of knitr has provided an extensive help and demo site(examples).
