I tend to have a lot of packages installed, in part because of a wide diversity of interests and a disposition of examining different ways to accomplish a given task. I am looking for a better way to upgrade all my packages when I upgrade the version of R that I am running. On looking at support for installing and updating packages, I found these two: installed.packages() and install.packages() and it occurred to me that in principle I ought to be able to use the one in the original installation to get a list of packages I'm working with and and put its output into a plain text file that I can read in the new installation and pass to the other to ensure the new installation has a fresh installation of all the packages I want to work with.
I must be missing the obvious, but what's wrong with update.packages() ? ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
