Thank you for your reply. Do you have any idea of how to get rid of the errors? I tried Null function to calculate eigenvectors and nearPD to get approximate positive definite matrix first but they also had errors. -- View this message in context: http://r.789695.n4.nabble.com/error-code-1-from-Lapack-routine-dsyevr-tp4702571p4702639.html Sent from the R devel mailing list archive at

...f eigen untrace(eigen) If all goes well then eigen(lastEigenX) will cause the same error and you or someone on this list can see what is odd about that matrix (e.g., by looking at its singular values).

...Preferably *not* this list as this doesn't really seem to be about developing R or with/for it. R-Help would have been a more appropriate venue for a question such as this.

Hi, I got an error message in my program saying "Error in eigen(gene_intersection.kernel) : error code 1 from Lapack routine 'dsyevr' Execution halted". As you see, I was trying to compute the eigenvalues of a matrix but got this error. Is there anyone who knows what this error means and how I can fix it? Theoretically the eigenvalues should be nonnegative, if it helps.
