[R] matrix inverse in C

[Kosuke Imai]

Hi,
  I'm writing an R package using the C code i've written. I'm wondering if
anyone knows an easy way to calculate an inverse and cholesky factor of a
matrix using the Fortran/C library of R: and how to call them from C. My
code is based on the Numerical Reciepe code, and I'm trying to use
something that is already in R.
Thanks for your help in advance,
Kosuke
