My plan is to upgrade MATLAB on all computing nodes to R2015b which will take care of license issue with the minimal disruption to users. Unfortunatelly the upgrade will require that users logout and stop using MATLAB. Due to the IEEE next week deadline this is not the right time to do it. However I am on the top of the things so everyone please stay calm.

Thanks, > 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 Our installation of RStudio (IDE) is obsolete as upstream cares only for Windows.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.

I am serious. As you know both MATLAB and R are domain specific languages. The only data structure recognized by MATLAB is matrix. Two dimensional matrix of a finite subset of rational numbers. How are you going to put a string into the matrix? Ugly yeah! On the another hand basic data types in R are: - Numeric - Integer - Complex - Logical - Character which means that with exception of pointers R recognizes all classic primitive data types plus a buil-in data type "Complex" (Fortran lovers will remember that one). R has more packages for data mining and machine learning than any other language and this comes from a mouth of a Pythonista. Now why some nut cases like Peter and me like Python better than R. Well unlike R, Python is general purpose interpreted language which has two great libraries for dealing with data mining and machine learning Pandas and Scikit-learn. They are not quite as good as R (they are getting there) but we are completely unconstrained by the domain of application so important to R. We could also talk about other alternatives like Perl, Haskell, Julia, Lua alike.

R and Python reign supreme. Julia and Scala are likely usurpers. The mention of Haskell makes me glad, but Scala does just as good a job as a language and a platform.
