The R-admin manual section 6.6 talks about "mac.binary" to refer to macos binary packages but I don't think this is working. On R-4.4.2:
contrib.url(repos = 'https://cran.r-project.org', type = 'mac.binary') # "https://cran.r-project.org/bin/macosx/contrib/4.4" This URL is 404 because it is missing the /big-sur-arm64/ dir in the path. For the same reason we get an error: install.packages('MASS', type = 'mac.binary') I think in practice only type = "both" currently finds the correct binary packages? _______________________________________________ R-SIG-Mac mailing list R-SIG-Mac@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-mac
