[adegenet-forum] DAPC and morphological data

[Maéva Angélique TECHER]

Dear all,

I'm trying to perform a DAPC on a morphological dataset which is composed of 176 variables of distances for several populations. 

The dataset looks like this:

> head(jeu)
      POP   X1.2   X1.3   X1.4   X1.5   X1.6   X1.7   X1.8   X1.9  X1.10  X1.11  X1.12  X1.13  X1.14  X1.15  X1.16  X1.17  X1.18  X1.19   X2.3   X2.4   X2.5   X2.6   X2.7   X2.8   X2.9  X2.10
CAF1.1 CAF 0.0837 0.2564 0.3150 0.3667 0.3266 0.2661 0.1942 0.1823 0.1133 0.1667 0.1409 0.2364 0.3959 0.7171 0.5261 0.4894 0.3896 0.4618 0.1742 0.2350 0.2841 0.2773 0.2304 0.1756 0.2089 0.1411

I tried to input the matrix in R using Adegenet and the function df2genind. My problem is that R stopped the importation and posted this message:

> morpho<-df2genind(jeu[,1:177], missing = 0, ploidy = 1, type = "codom")
Error: C stack usage is too close to the limit 


Is the problem coming from the variables which are not integers or from the importation script?

Thank you very much for your help,
Cheers, 
Maéva
