We see this from time to time and it usually means there s something
degenerate with a fit, but we haven't been able to get to the bottom
of it. Without reproducible examples I don't have the time to track
this down further.

Dear members

I find continuous error message while running anova by "axis" in rda
analysis using "vegan" in r as follows:
Error in La.svd(x, nu, nv) : error code 1 from Lapack routine 'dgesdd'

The code I used is anova (model, by = "axis")
Similar code used for anova (model, by = "ma") works with no error

I have gone through previous mails of this forum but I am confused what
actually I should do with this error. Your advice is highly acknowledged.

With best Regards
