Have a look at http://adv-r.had.co.nz/Environments.html#function-envs ..and a much briefer (if a little less detailed) explanation in https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Package-namespaces + + + + + And Hadley, if you're reading this (if you're not I suppose it's a waste of bandwidth): Thanks very much for "Advanced R" It has been of immeasurable help to me. I see you've put answers to (at least) some of the exercises. This is a good thing. When I worked through it last I usually came up with *an* answer to one of the exercise, but often I had little clue as to whether or not it was the (or a) correct answer (not you're writing, my brain turned into a brick a decade or two ago, before I'd even heard of R). So thanks also for your continuing work, and I get to go back over it again. Cheers all. ____________________________________________________________ South Africas premier free email service - www.webmail.co.za ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
