Hi- you are trying to install a package, which will download data from the Internet. Not all sites are available through sagemath cloud. If you pick a mirror that is accessible this should work so try install.packages("psych", repos="http://cran.cs.wwu.edu/") Make sure that you say "y" (yes) to install the package locally. Installing package into ‘/projects/<some_id>/R/x86_64-unknown-linux-gnu-library/3.1’ (as ‘lib’ is unspecified) |
