Hi,
I'd like to realise a sPCA analysis with adegenet but a little bug 
appears during the "connection network choice" step. I'd like to know if 
someone could help me for that.
I'd like to use the Delaunay triangulation type (type1) but when i 
choose this option, i get this error message : "Error in tri.mesh(x = 
coords[, 1], y = coords[, 2]) : duplicate data points". I think it's 
because my data game contains some samples with the same spatial 
coordinates. I'd like to know if it's possible to keep this samples in 
the analysis (i've seen that R can automatically delete all the data 
with repeated coords or keep only one of these samples/coord but this 
solution doesn't suits me fine), and if yes, how should I do ?. Thanks 
for your help. (The coord file is attached to this message, maybe it 
could help)
Thanks a lot
