Hello, I am supernew to R. I wanted to open an RMarkdown file, but first I was prompted to run an update. THis is the error message:
Installing 'markdown' for R Markdown...

Any help welcome!

R has problems with cloud-synced folders (Dropbox in your case), I recommend you to set your package library in a non-synced folder.

You can change the default library folder by setting your R_LIBS_SITE environmental variable in a .Reviron or .Rprofile file. For example:

# In a .Renviron file you can set it by adding a line like this one with the desired location 
R_LIBS_SITE="C:\\Program Files\\R\\R-4.1.2\\library"
