I keep receiving this error messages .I've already installed Rtools and I don't know what to do.Please help.
Error in install.packages : cannot open file 'C:/Users/user/OneDrive/Documents/R/win-library/4.1/file2ca018f6568/pacman/pacman_logo/r_pacman.png': Permission denied
R has problems with cloud synced folders (OneDrive in your case) I would recommend setting your default 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 one with the desired location
R_LIBS_SITE="C:\\Program Files\\R\\R-4.1.1\\library"
For a more detailed explanation, you can read this blog post
Also, this seems like a connectivity issue, R is not being able to connect to the CRAN repository you have selected, these are some things to try.
Choose a different CRAN repository, RStudios repository is a good choice (http://cran.rstudio.com/) or you could choose one that is geographically closer to you.
Check if your internet connection has traffic restrictions of some kind, like a firewall, proxy server, etc. This is usually the case when you are at work or school.
