Or maybe it used in another place in the IDE.Īnyway, just wanted to inform you of this change in **knitr** So maybe in a future version, the requirement could be often when knitr 1.34 is used. However I don't know how the dependency graph is working but it could be suprising / puzzling for user to have a missing package after a successful `install.packages('rmarkdown')`. This is not really an issue because the **markdown** can be installed safely (by anwsering yes to install when IDE is asking). * This package is no more required and `rmarkdown::render()` works ok to build the doc.

* Try to knit the document using the IDE button - a message from the IDE ask me to install the markdown package. * Restart the project using the isolated renv library where markdown is not there. * Install packages with last CRAN versions - **markdown** package won't be install anymore * Create a new renv project with rmarkdown document I believe this is causing the behavior I am seeing:
