Hi Thimbaut and adegenet users
Thanks for your help on getting the package running. All working now.
I am attempting a DAPC on a genind object containing no missing data with 264 isolates and 24 microsat loci with the arguement:
dapc <- dapc(obj, pop=NULL, n.pca=NULL, n.da=NULL, scale=TRUE,scale.method=c("sigma"), truenames=TRUE, all.contrib=FALSE,pca.select=c("nbEig"), perc.pca=NULL)
Choose the number PCs to retain (>=1): (I put 2 - 15)
Message returned is:-
Error in svd(X, nu = 0) : infinite or missing values in 'x'
In addition: Warning message:
In .local(x, ...) : Some scaling values are null.
Corresponding alleles are removed.
Any advice most appreciated
Thanks
M
