Hi, I was wondering if it is possible to lock a package to a specific version of R. Dependency attribute in the package DESCRIPTION only accepts>= AFAIU
Depends: R (>= 2.13.2), R (<= 2.13.2)
Or even use ==
Dear Professor Ripley, Thank you for the reply. We are maintaining Internal R packages and build binaries for different versions of R base, ranging from 2.8.x to 2.13.x We need to prevent users using "wrong" versions, but the ones we tested. (we distribute binaries only and package source base is evolving as well) Not sure how to address this, initially I was thinking to put R version in the package version, but package version in description files only allows x.x.x format which doesn't give a room.
I don't see why you would want to do this: why would a package work with 2.13.1 and not 2.13.2, or 2.13.2 and not 2.14.0? Ranges may make sense.
Ranges would be much more sensible then "==".
Best Regards,
Mehmet
