Hi Andreas,
I have just finished my package of r-cran-ape, so you can find it on
https://bitbucket.org/Dybian/package-debian-r-cran-ape
I tried it and it seem to work fine (install, uninstall and run in R), I have only one warning with lintian about that a new package should close a ITP bug.
What do you think about it?
Dylan
