Hi all, We know old.packages() can check for updates of add-on packages, but is there a way to check updates of R itself? "go to R homepage" is a way, of course, but I hope this can be done by R.
I'm not sure about the "reliable" place to check; here is a simple example to check from one of the CRAN webpages (kind of nasty approach...): x = readLines("http://cran.r-project.org/sources.html") # the version number is in the next line of 'The latest release' rls = x[grep("latest release", x) + 1L] newver = gsub("(.*R-|\\.tar\\.gz.*)", "", rls) oldver = paste(getRversion(), collapse = ".") # new version available? compareVersion(newver, oldver) == 1L Thanks!
