Thanks for taking the time to read my message and for the constructive
idea. You are right that it is a bit late for us to do this now. Given
that spatstat (<=1.65) exports >2,500 objects which are now spread
across sub-packages we would obviously have to make a script to help us
reexport the functions and make documentation containing links to the
real man page. This might be doable, but one big downside is that we
then don't use this occasion to move package dependencies from spatstat
to the relevant spatstat.xxxx. If the packages don't fail I'm afraid
that a lot of maintainers wont change anything, and their package will
depend on the entire ensemble of spatstat packages rather than just the
relevant sub-package(s). For our usual end users this would also mean
that when they open the help file of given function after attaching
spatstat it will just contain a huge list of links to the real help
file they are looking for which is a nuisance.
Unless we get other really good suggestions we will wait a bit more on
a reply from CRAN (we sent a gentle reminder a week ago) and hopefully
learn what we should do differently to get the last bit in place.
