Subject: svd in shapes[R]

Hi to all,
I'm having some problems when I try to perform a GPA on a particularly
large dataset with the package shapes [ R ]. The error msg is:
Error in La.svd(x, nu, nv) : error code 1 from Lapack routine 'dgesdd'
I have 495 shapes with 68 2d landmarks. I've tried to make some subsets
and to remove some landmarks to identify the problem. The problem seems
to correlate with the size of the dataset, but I have already used the
same script on a larger dataset and got no errors. I was also able to
perform multiples GPAs on smaller samples within the full set and,
again, got no errors.
A quick search on the web showed that other people had similar problems
while trying to perform a svd and also asked if it was related to the
size of the dataset, but I found no solutions.
If anyone have any idea how to solve this, I would appreciate the help.
cheers,
