Generator Microsoft Word 11 (filtered medium) Hi,

I'm the mannova package maintainer. We used La.svd(X, method="dgesvd") in maanova package before. After R-2.3.0, the old La.svd() method was deprecated for option method="dgesvd". I changed maanova code correspondingly, which will call method="dgesdd" instead. But after that, we keep getting below error message from La.svd() if the data object is big.

Error in La.svd(X) : error code 1 from Lapack routine 'dgesdd'

Would you please help us to figure out what's the cause of this? We tried the small and big microarray data set. Small one does not cause this problem, but the bigger dataset causes this error. Is there any limitation of using La.svd() or is there any parameter we can specify to enlarge the capacity of La.svd()?

Please see the attached R script and data files. Sorry for the huge data file. But that' s the smallest I can make to cause the error message.

Thank you very much for your help!

Lei
