I have added it now: Under development. DO NOT USE: it will break things. - Under no circumstances would I use c2d4u3.5 for anything other than testing. As Dirk mentioned, I haven't announced it yet. It is incomplete and at any moment, it will break your system. In an hour, it may not break your system. - This will take time. To rebuild the entire hierarchy of packages, in order, for three different releases, will take a lot of time. Trying to do this a quickly as possible, but family and job have a higher priority. - Trusty is becoming increasingly difficult to build for, especially with Bionic added to the mix. Non R packages have changed names, which can prevents a large number of packages from being backported. I will be trying different solutions in order to build as many packages as possible while making the process robust. - I do appreciate notes about things not working, as I can't test every possible combination. The best method is to send me an email, since this is still a work in process. Bottom line: If you rely on Ubuntu providing as many packages as possible for your R experience, the R 3.5 c2d4u-verse is not ready yet. When it is, I'll let you know.
