[R] Computing generalized eigenvalues

[Joshua Gilbert]

I need to compute generalized eigenvalues. The eigen function in base
doesn't do it and I can't find a package that does.

As I understand it, Lapack __can__ computer them
(http://www.netlib.org/lapack/lawn41/node111.html) and R can use
Lapack. If there is no function already, can I access Lapack from R
and use those routines directly?

Thank you,
Joshua Gilbert.
