+%description java
+A language and environment for statistical computing and graphics.
+R is similar to the award-winning S system, which was developed at
+Bell Laboratories by John Chambers et al. It provides a wide
+variety of statistical and graphical techniques (linear and
+nonlinear modelling, statistical tests, time series analysis,
+classification, clustering, ...).
+
+R is designed as a true computer language with control-flow
+constructions for iteration and alternation, and it allows users to
+add additional functionality by defining new functions. For
+computationally intensive tasks, C, C++ and Fortran code can be linked
+and called at run time.
+
+This package also has an additional dependency on java, as provided by
+Fedora's openJDK.
