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 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?
So some reason I am able to knit my R markdown file into a Word doc. I don't know what to do or how to get over it. I keep getting the message in the picture about the code also listed there.
My R markdown file is working fine, until I add a particular plot, then it will not knit and displays the following error:
! LaTeX Error: File `filename_files/figure-latex/unnamed-chunk-2-1' not found.
When I remove the plot, the file knits, when i include it, it doesn't knit. Here is the code I'm using for the plot:
```{r echo=FALSE}
plot(x=variable1,y=variable2,main="plot title")
```
I'm at a loss as to why this isn't working, when I've got other plots in the document that are displaying fine and are knitting in the pdf.
Rather frustratingly, I have managed to get around the issue by copying all of the text into a new document, and then trying to knit, and it worked straight away... However, after a while, the same issue kept occurring, this time with a different plot. A further workaround seemed to be rebooting the laptop. Again, I'm not entirely sure what is causing the issue, but it was occurring intermittently and without warning.
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.
If I have an R block in an Rmarkdown notebook, the code is visible in the rendered nb.html file. However, if I have a SQL block, I can't find a way to make the code visible in the rendered file.
However, if I generate an html_document (standard knitr) instead of an html_notebook, the rendered HTML does include the SQL code (and output).
Is there a way to get the notebook output to do something closer to what the knit output does?
I've also encountered this recently, Harlan, and began by asking if there's a way to get notebook output more like knit output.
I then wondered if there was a way to get knit output more like notebook output and realised that there was.
After asking the folks at RStudio, I learnt that you can add the following line to the YAML options in order to generate a html_document that, when rendered, enables the RMD to be downloaded. Specifically, use:
output:
html_document:
code_download: true
I now use that in all of my code and it works well. I hope it helps you, too.
