I'm not saying "supposed to" I'm saying wise to. And the "IMHO"s above were what I really meant. By all means, you're free to do anything as long as you don't ask on the mailing list that something doesn't work because you ran it on a stale directory ;). > Do you have any convenient shortcuts to overcome the fact that the > binary package contains the package name? i.e. how can I build and > install/check in a single line without having to specify the full file > name? > > How can I go from: > > R CMD build plyr && R CMD install plyr_1.5.tar.gz > Some will argue that's an invalid command to start with ;). But other than that I see nothing wrong with it ... it's what I do to be honest ... (except where I don't, but that has to do with my custom build script legacy which has a defined way to get versions on the shell, long story...). > to > > R CMD build-and-install plyr ? > R CMD build plyr && R CMD INSTALL plyr_* ... if you don't keep too many version in the same directory ;) - but it's not something I would use. For the paranoid R CMD build plyr && R CMD INSTALL plyr_`sed -n 's/Version: *//p' plyr/DESCRIPTION`.tar.gz But, seriously, that is the least problem I see - you'd have to advance your version numbers very quickly to get the version command out of your shell history...
