problems using square brackets within \Sexpr in Sweave files

[nickreich]

I have run into a problem when trying to use \Sexpr{} in Sweave files in RStudio Version 2023.12.0+369 (2023.12.0+369).

The problem is best demonstrated in the image below. I have noticed that when I use square brackets within an \Sexpr{} tag then all of the text (not code) after that tag is interpreted by RStudio as code, and not text. This seems like a bug in the IDE to me. And I will note that this was not happening to me a few months ago. So it seems that in an update of RStudio or maybe knitr something appears to have changed.

This seems like a bug in the IDE to me. And I will note that this was not happening to me a few months ago.

If this is happening only in the IDE source mode, this would need to be reported in GitHub - rstudio/rstudio: RStudio is an integrated development environment (IDE) for R if not there already.

If rendering / knitting works ok, usually rmarkdown or knitr is working. Try outside of the IDE to check if it is involved.

Thanks !

Yeah, it does work outside the IDE, so it seems to be an issue with the source mode in the IDE. I will file an issue.
