While this would create a versioned dependency relation which would
allow to migrate r-cran-epi to testing I'm personally lacking the
technical knowledge whether this is the correct solution. From my point
of view the correct approach would be to create an r-base-core package
which declares a stable ABI and packages should depend from the ABI
version. However, its way to late for implementing this in Jessie and
the R maintainer is not willing to do this anyway (at least he was not
when we discussed this in Wheezy freeze time[1]).
Kind regards
Andreas.
