This message is a usual one. Often you don't have write permission to where R is installed . When you only have this system library (and no personnal library), R will try to use the systeme library for installing package. But you don't have write access . This why you got this message
Warning in install.packages :
'lib = "C:/Program Files/R/R-4.0.3/library"' is not writable
That is why you are given a choice to use a personal directory when it is not created. This personal library is in your home folder, usually Documents/ on your user's space. However, in your case, it seems you don't have write access to this folder too.
Warning in install.packages :
cannot create dir 'C:\Users\bhaum\Documents\R', reason 'No such file or directory'
Error in install.packages : unable to create ‘C:/Users/bhaum/Documents/R/win-library/4.0’
Outside of R, are you able to create this folder in Documents/ ?
You need to have a R library folder in a space where you have write access.
