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

[Ulrich KELLER]

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:

> library(rpart)
Error: package or namespace load failed for ‘rpart’:
 package ‘rpart’ was installed by an R version with different internals; it needs to be reinstalled for use with this R version
> installed.packages()['rpart',]
                                    Package
                                    "rpart"
                                    LibPath

                                      Built
                                    “3.4.3"

Package r-cran-rpart was updated though, as "apt-cache show r-cran-rpart" lists the package file as "xenial-cran35/r-cran-rpart_4.1-13-1cran1xenial0_amd64.deb". No other version of rpart is installed. It seems that this Ubuntu Xenial package has to be updated with a version of rpart what was built with R 3.5 (instead of 3.4.3).

Thank you for the otherwise great work and kind regards,

Uli Keller
