Error package installation

I am starting with R. I installed the latest version of R and R-Studio today.

I need to import a large excel file. Then the following problem goes:
WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:
Installing package into ‘C:/Users/Acer/Documents/R/win-library/4.0’
(as ‘lib’ is unspecified)
Warning in install.packages :
package ‘readxls’ is not available (for R version 4.0.2)

Then I followed these instructions

but still there is the problem I cannot install packages. at least those i need right now.

I cannot find a package called readxls. Do you mean readxl? Try


Yep. Thanks. It has changed names. Plus, You need to add double \Documents\ba,,, for paths... just in case someone new reads this.
