Installing R-devel from http://r.research.att.com/
Hi all, I suspect this is an easy question... How do I install R devel from the various snapshots provided on http://r.research.att.com/. [I generally build from source, but need to assist people in getting a working R-devel on OSX for a course we are teaching] The website says: The installer image (*.dmg) is packaged exactly the same way as the CRAN release of R (including the GUI) and it will update your R version (unless you delete the last receipt). The installer image is too small to contain everything (52kb) and I don't understand what is meant by "unless you delete the last receipt". I've tried the installer and it tells me it can't open R.mpkg. Thanks, + seth
