Actually after trying to downgrade your version of R for about 45
minutes I realized that is a wrong way to deal with the problem.
Downgrading packages is very difficult as all dependencies have to be
resolved manually. In system administration we call that Red Hat Hell.
The real way to deal with your problem is to upgrade manually installed
package. Kyle brought to my attention that automatics updates of R
(which I turned on)  are braking manually installed R packages. There is
a way to deal with it. I just need to read about 20 pages of the
documentation before I can do it.

Between plotting in R shell is broken since last week due to shady QA by
EPEL people. I am hoping that the upstream will fix the problem soon and
that will not have to "downgrade" things.

Finally Dr. Dubrawski have overheard me using word obsolete in the same
sentence with R. Our R is the latest and the greatest (or maybe not so
great). Our installation of RStudio (IDE) is obsolete as upstream cares
only for Windows. The upshot of having the old version of RStudio is
that R plots still work from it.

Best,
Predrag
