Try this:

options(repos = c(RSM = "https://radiant-rstats.github.io/minicran", CRAN = "https://cloud.r-project.org"))

Or visit the Github for more info about the package:

Error: package 'radiant' is not available
In addition: Warning messages:
1: In value[3L] : restarting interrupted promise evaluation
2: error downloading 'https://radiant-rstats.github.io/minicran/src/contrib/PACKAGES.rds' [curl: (22) The requested URL returned error: 403 Forbidden]
I have tried then it's giving this error

That's weird as I can easily install the package. Do you have the last version (most updated) of RTools?
