I cannot find what is the function label for matrix inversion in R. I have found 'ginv' for the moore-penrose in the MASS package, but there is probably a simple inversion operator in the base package. Where can I find it? ____________________________________________ Yvonnick Noel, PhD.

how about solve() ? solve(A) yields the inverse of A. jose ramon albert manila, philippines ----- Original Message ----- From: Yvonnick Noel <noel at univ-lille3.fr> To: <r-help at stat.math.ethz.ch> Sent: Friday, September 29, 2000 8:34 PM Subject: [R] Matrix inversion> I cannot find what is the function label for matrix inversion in R.
