Dear R,

I have a problem concerning the inverse of a matrix. My matrix is quite
large and I extracted just linearly independent columns from the matrix.
However, the function solve() still cannot invert the matrix - I get an
error that it is computationally singular. Is there any way how to extract
some columns from the matrix so that I could get the inverse?
The problém is I can extract a "nonsingular" matrix but there is no point
in doing it since I don't get the inverse.

Thanks
Sarka
