[Rd] non user-friendly error for chol2inv functions

Hi,

In function chol2inv with the option LINPACK set to false (default), it raises an error when the matrix is 1x1 matrix (i.e. just a real) saying

'a' must be a numeric matrix

This error is raised by the underlying C function (modLa_chol2inv in function Lapack.c). Everything is normal, but I wonder if we could have another behavior when we pass a 1x1 matrix. I spent time this morning finding where was the error, and it was this "problem".

Thanks in advance

Christophe
