Interesting article.  Thanks for bringing it to our attention, Joe.

There are a couple of quotes that I like, such as "It's simply amazing
the things that you can learn when data is presented in a graphical
format." 

It appears that the author is using <<- when he only needs <- in one
function definition.  There isn't anything peculiar about PL/R that
would require <<-, is there?

Also, there are a couple of "Don't try this at home, kids" typos like
using

 apt-get install R

which I think should be

 apt-get install r-base

or even

 apt-get install r-recommended

(The Debian packaging system doesn't allow upper case in names, which
is why I called the original Debian package "r-base".)
