Hello! I ask for advice on downloading the devtools package for R studio. Install the package through the official CRAN repository. The update package does not require. The library ("devtools") command returns the following message: Error: package or namespace no package called 'fs'. Please, suggest what to do in this situation.
P / S I need this package to download the install_github ("bdemeshev / rlms") package — I just can't download it.
