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
(http://cran.r-project.org/doc/manuals/R-exts.html#fn-3 )
Any work around?
Intervals are possible., and you can restrict them to one version as follows:
Depends: R (>= 2.13.2), R (<= 2.13.2)
Or even use ==
The point of the footnote is that install.packages() will download a
package only checking any >= requirements (and I suspect it will then
install a binary version of a package). R CMD INSTALL will not
install it from the sources, and library() will not load it.
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.

Thanks,
