• Notes from Thomas Lumley's two-day short course in R
• Video R Tutorial

• Short well-organised html R Tutorial with that National Geographic look
• Yet another html R Tutorial, one big page with nice graphics and examples

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.)
