I need to use devtools, every time i type in library(devtools) i get this error message:
Error: .onLoad failed in loadNamespace() for 'pkgload', details:
call: loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]])
error: namespace ‘rlang’ 0.4.0 is already loaded, but >= 0.4.1 is required
I have tried multiple times to update the package. I've tried other site suggestions. To no avail.
Thanks in advance.
