dear list,
since matrix manipulations is often of interest in statistical
computations, i'd like to get a working example of using Lapack for
regression. However, i run into an error.
My matrix-lapack-example.c file:
thank you William Dunlap and professor Bates for your responses.
Since the first argument is always an N for linear regression, i
just placed
const char* trans = N;
in my .c file and things worked.
See some comments below.

i meant .Call(). also, sorry for
