FYI the smallest eigenvalue option is available in the stable version on CRAN. I'll try to reproduce on a windows machine. Unfortunately I don't have ready access to one --...

the current cran version is 2.3.2, see https://cran.r-project.org/web/packages/irlba/index.html not sure why you've got such an old version? On Thu, Jun 21, 2018, 11:48 vdebuen wrote: > Sorry but I don't...

Any update on this? Were you able to get things to work? FYI a new release is pending, will be on CRAN soon...

Thanks, this is a good suggestion. I will work in a solution to this, probably using the sign of the 1st element of the first u vector. ---

Thanks, this is in fact a different, more serious, problem than the sign issue above--~~it's a bug!~~ EDIT: Whoops -- not a bug after all...see next long comment,

Sorry, this was not a bug, but it does show another example of the inconsistent sign issue that you already surmised abouve. You'll be happy that a partial fix for...

Sorry, the test failure is due to an unrelated issue that I forgot about. I think this new rng=runif option will fix your issue. If you agree, we can make...

Sorry for the super-long latency. Crazy summer. A few notes: Just S$v above only uses the first singular vector as a starting vector for the Lanczos process. This can indeed...

OK, sorry I misunderstood. I see your question now. The initial vector can help, but the implementation of irlba uses matrix vector products. A block implementation would probably benefit more...

Thanks for this report. I've had some offline discussion with Jim Baglama about improving the restarting code more generally as well. In the short term though I'll try to fix...
