Followed the instructions, from here to install the latest R: https://cran.rstudio.com/bin/linux/suse/

Basically:

Code:
sudo zypper addrepo -f \
     http://download.opensuse.org/repositories/devel:/languages:/R:/patched/SLE_12/ \
     R-base
sudo zypper in R-base
Unfortunately, as of today 2/19/2018, this command no longer works. It is looking for a new xdg-utils

Code:
Problem: nothing provides xdg-utils needed by R-patched-3.4.3-798.1.x86_64
 Solution 1: do not ask to install a solvable providing R-base
 Solution 2: break R-patched-3.4.3-798.1.x86_64 by ignoring some of its dependencies
Installing `R-core` is also broken. It is looking for libcairo:

Code:
Problem: nothing provides libcairo.so.2()(64bit) needed by R-core-3.4.3-798.1.x86_64
 Solution 1: do not install R-core-3.4.3-798.1.x86_64
 Solution 2: break R-core-3.4.3-798.1.x86_64 by ignoring some of its dependencies
