[adegenet-forum] supplementary individuals

Hi Thibault,

I am trying to use the pred.sup function to assign 'test' individuals against my baseline data. Both baseline and supplementary individuals files load fine in adegenet but when I run the pred.sup function I get the following:

Error in predict.dapc(dapc1, newdata=sup):
                Number of variables in newdata does not match original data.

Looking at the dataframes, the baseline says it's a matrix of 1800 x 70 (which I expect), however the supplementary says 69 for the latter(?). I have found that when  interrogating @loc.fac for the supplementary file, locus27 is only listed once, while all others are listed 2x. Perhaps a coincidence but this locus is the only one that is monomorphic  in the supplementary individuals but it is polymorphic in the baseline - would this have any effect?
