Re: [R] eigen vector sign reversal

[Roger D. Peng]

I think at version 1.7.0 R started using LAPACK for its eigen/svd 
routines.  I think using `eigen(x, EISPACK = TRUE)' uses the previous 
version.

I've just installed R 1.7.1 under linux red hat
I noticed sign reversal of eigen vectors ,some of them not all, upon
using diag function relative to those obtained using R 1.4.1
this is gonna miss up lots of my previous scripts
I wonder if there is a way to avoid this.
best regards
