Learn R Because it is Hot

R is so hot right now.

Functional programming Schemers like myself have spent years whining about how just because something like Cobol or Fortran or C or C++ or Java or perl is "hot" or "standard" or "used by highly profitable companies" or "easy to get a job if you know" does not mean it is actually good or worth learning. Well now the shoe's on the other foot, suckers: R is Hot!
(Update: machine learning is so hot.)
