R 3.3.1
A free programming setting to make statistical studies.
R is a professional programming setting to make statistical calculations and studies, from which you can do statistical and graphical tests, whether linear or non-linear models, temporary series analysis, classifications, clusterings, etc.
R comes equipped with all the usual elements of a programming language, so you can control flow, use syntax to create interactions and possible alternates, create new functions to do specific actions, etc.
It is very interesting that R also lets you link and reference source code in C, C++ or Fortran.
