package fpc
is not available (for R version 3.5.3)
I have tried a few methods:
github_pkgs <- c("cran/Rstem")
install_github(github_pkgs)
install.packages("fpc", repos= 'http://cran.us.r-project.org')
install.packages("fpc_2.1-11.2.tar.gz", repos = NULL)
Thank you if you can help me out of this loop...
None of them works
