I am trying to print a long code, highlighted with R syntax, at the end of my thesis, written in R markdown. I am knitting to pdf. I receive the error: ! Dimension too large.
I am copy pasting my code into the document:
```R
Pasted code
```
I was wondering if there is a way to avoid the error when printing my code in R markdown.

I am writing an .Rmd file in VSCode using the VSCode R extension. The extension does a great job of highlighting and code completing r code inside code chunks. However, it does not highlight, or code complete, inline Latex code.
For example, this is how my inline Latex code looks like:
Now, if I change the language mode from R Markdown to Markdown as indicated in this question VS Code Latex Syntax in Markdown, then I get great Latex code highlighting and completion, as shown below:
However, when I do this I loose all highlights and completion for the r code inside the code chunks.
How do I set things up so that I have highlights and code completion for code chunks and inline Latex code?
Recently I was doing a course in Coursera and faced the problem while doing R markdown. When I run the code in the console it works just fine however, when I knit it, the rmarkdown only show text in the code chunk as below.
I run this in console and it work just fine:
But when i knit the code appear as text:
When I hit the green arrow it appears like there are some error going on:
The bottom screenshot you provided is not an R code chunk. It does not have the proper header. R code chunks in an R markdown file must be formatted like this:
```{r}
R code goes here
```
I'm trying to insert LaTeX code into a figure caption created by knitr. I have the code below in a .Rnw file and I'm converting it to a .tex file using knitr:
<<my_plot, fig.cap="X is $\leq$1 and Y is $\geq$2">>=
plot(1,2)
#
Code as it stands give an error. How can I use insert the LaTeX code into the figure caption?
I'm trying to use knitr to inject R code and its output in pandoc/markdown documents. But I do not get knitr to inject the R output. I have tried decorating the R chunks with r and with{r}. Both doesn't work. Here my sample setup (with ```r):
First I show the command I issue, then I list the two files subsequently used by this command.
Here the command for the shell:
$ r CMD BATCH knitme.R
Content of knitme.R:
library("knitr")
pandoc("foo.md")
Content of foo.md:
# My knitr test
```r
1+1
```
Did this print *the result* as well?
Here a graph:
```r
plot(1:10)
```
And where is the graph?
After I ran the command I do get, as expected a new file foo.html. Here its content:
<h1 id="my-knitr-test">My knitr test</h1>
<pre class="sourceCode r"><code class="sourceCode r"><span class="dv">1+1</span></code></pre>
<p>Did this print <em>the result</em> as well?</p>
<p>Here a graph:</p>
<pre class="sourceCode r"><code class="sourceCode r">
<span class="kw">plot</span>(<span class="dv">1</span>:<span class="dv">10</span>)</code></pre>
<p>And where is the graph?</p>
This result shows that pandoc converted the input file foo.md, *but knitr did not inject the Output of the execeutes R code.
What do I miss? any help appreciated!
You should first call knit() on an R Markdown (*.Rmd) document, which produces a Markdown (*.md) document, and that is when you can run pandoc().
library(knitr)
knit('foo.Rmd')
pandoc('foo.md')
The R scripts in examples 084 and 088 as mentioned on the flaky website have illustrated how. Please also take a look at the Rmd documents to learn the syntax for R code chunks in R Markdown. If you still have 5 minutes, watch the video on the homepage, and I think all the confusion should be gone.
I really like using knitr in Rstudio and have been using it to write markdown presentations and data analysis. I want to use the same code and results in a paper and want to convert the code chunks in Rmd file ```{r} to the chunks of Rnw file << >>= #.
This allows using the same document and code written for presentation for the main paper as well.
Is there a way of converting between code chunks of markdown and Rnw files ?
or the entire file itself as apart from the difference in syntax of code chunks, they are quite similar in the markup (converting the text to latex is easy with say pandoc)
Instead of converting the whole document, you can just externalize your R code so it can be shared across different documents; see http://yihui.name/knitr/demo/externalization/
Once you have read_chunk('Rcode.r'), you can use ```{r label} in your Rmd and <<label>>= in your Rnw document, where label comes from the line ## #knitr label in the R script.
