https://cran.r-project.org/web/packages/splines/index.html claims the the {splines} package has been archived. If I follow the link there to the archives, the newest version shown is from 1999. It seems like something has gone wrong with this package.
I checked on another mirror and {splines} is missing there as well. —rjp ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
