+Python interface to the R language.
+
+rpy2 is running an embedded R, providing access to it 
+from Python using R's own C-API through either:
+
+1) a high-level interface making R functions and objects 
+just like Python functions and providing a seamless 
+conversion to numpy and pandas data structures
+
+2) a low-level interface closer to the C-API
+
+It is also providing features for when working with 
+jupyter notebooks or ipython.
+
+NOTE:
+R needs to be compiled with the shared library flag,
+thus: build R on SBo with R_SHLIB=yes and BLAS_SHLIB=yes

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
