i meant .Call().   also, sorry for the poor word choice, i meant
matrix computations, not matrix manipulations.  i guess i just want
some recommendations for future references on what C library to use if
i were doing something like re-implement linear regression
(hypothetically speaking).  i assumed it would be lapack.  is this the
recommended approach?
