Re: [Rd] In creating a Windows binary package (zip), how do I make the installation configurable

You could look at the Ryacas package for some ideas. zzz.R in

is invoked at library(Ryacas) checking whether certain binaries are present and if not present then issues a message telling the user to run yacasInstall() without arguments. yacasInstall() in:

downloads the required binaries into the appropriate place. (Although Ryacas runs on UNIX, Mac and Windows the yacasInstall functionality and associated binaries are only available for Windows currently. Manual installation is required on UNIX and Mac.)

It would have been possible to have zzz.R call yacasInstall() directly but we felt that downloading files to the user's computer transparently was not a good idea and we should make the user issue a specific command to do it to ensure that they really want to allow that. Also it gives the user the possibility of doing it manually instead of using the automatic procedure.
