[adegenet-forum] what does 'd = ' mean in pca plots

[Jason Paul Joines]

adegenet Users,

         I used the scatter function to plot the glPca of a genlight object 
as shown in tutorial-genomics.pdf.  The plot includes a small inset 
barplot of Eigenvalues in the bottom left corner.  The top right corner 
has the text "d = n" where n is a number that differs from one plot to the 
next.  What does "d = n" represent?


Thanks,

Jason
