[R] About lm.ridge in the MASS package

[baghaliforoosh@Yahoo.com]

Hi,

I had a questions about doing ridge regression in R. 

Why is it that when I try this on datasets with more predictors than samples (p>n) using lambda=0, it still finds coefficients for all predictors? I thought when lambda=0, it should be like ordinary regression and therefore not find coefficients for all due to singularity? 

I would greatly appreciate your help.

Thank you,
