Unable to install dplyr on R-4.0.5

Question

Trying to install dplyr on R-4.0.5

When I do install.packages("dplyr") ,

I get the following error,

Installing package into ‘C:/Users/Pragyaditya Das/Documents/R/win-library/4.0’
(as ‘lib’ is unspecified)
also installing the dependencies ‘purrr’, ‘generics’, ‘tidyselect’


  There is a binary version available but the source version is later:

Please help me. TIA.

Answer 1

I solved the problem by naming the default Rtools installation folder and ming_w32 folders as the installer was searching.

So, changes done were:

Rename Rtools as rtools40 & Rename ming_w32 as mingw32 in the root folder of RTools installation.

This solved the issue.

Answer 2

More specifically, rename C:\RTools to C:\RTools40 and rename C:\Rtools40\ming_w64 to C:\Rtools40\mingw64 (not sure this is necessary since the root folder is already renamed)

After these changes, I was able to install the dplyr package and load the library.
