Colinearity Function in R
Is there a colinearty function implemented in R? I
have tried help.search("colinearity") and
help.search("collinearity") and have searched for
"colinearity" and "collinearity" on
http://www.rpad.org/Rpad/Rpad-refcard.pdf but with no
success.
Many thanks in advance,
Peter Lauren.
