This seems to be a problem with RTools, either install the binary version of the package or verify that you have the proper RTools version for your R version.

Also, setting your package library in a cloud synced folder (OneDrive in your case) brings installation problems very often so 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 on a .Reviron or .Rprofile file

# For example, in a .Renviron file you can set it by adding a line like this with the desired path. 
R_LIBS_SITE="C:\\Program Files\\R\\R-4.1.0\\library"

Why install.packages in an Rmd ? I find this often when people cut and paste a solution from the internet. Packages only usually need installed once. Then just load them with library/require
