To run Rmd chunks, RStudio seems to use knitr's code internally in
tools:rstudio environment. Curiously, it won't be updated even when I install the development version of knitr... Anyone knows when and where RStudio captures the knitr's code?
Some contexts: I tried to fix this issue, but the warning won't go away even when I install the patched version of knitr.
Here's steps to reproduce:
- Install the patched branch.
- Close and relaunch RStudio to make sure to have a fresh R session.
- Open a new R Markdown file, and copy and paste this Rmd codes.
- Run chunks by ▷ ("Run Current Chunk") buttons on the top right of the chunks.
Then, I think you'll see a warning which is supposed to be fixed at my branch...
