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"

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
