[R-sig-Debian] Xenial rpart package on CRAN built with wrong R version?

[Ulrich KELLER]

I manually downloaded the rpart package and installed it using dpkg, without removing the old rpart package first, and now everything works. During the installation, dpkg said:

Unpacking r-cran-rpart (4.1-13-1cran1xenial0) over (4.1-13-1cran1xenial0)

So again, it seemed that the new version had been installed, but it really wasn’t. I had no idea that something like this could happen. Huh.

Anyway, thank you very much for your help!

Hello,
I just upgraded my Ubuntu Xenial system to R 3.5.1 (from 3.4.?) by changing the sources.list entry and doing an "apt-get dist-upgrade". Everything works except loading the rpart package in R:

Not quite sure if this has been resolved.  I can confirm that the Xenial rpart packages on the RRutter3.5 PPA is indeed built against R 3.5.  The rpart packages on CRAN is the same as on the PPA, so I believe this is an isolated incident.

Sometime the dist-upgrade leaves a few breadcrumbs that need to be cleaned up.  If all else fails, remove the installed rpart package, download the correct binary from CRAN or the PPA, and install with dpkg.

Hope this helps,
Michael
