[adegenet-forum] Change color in scatter.dapc()

[Roman Luštrik]

It would seem it is currently impossible to color points individually. To do that, you'll have to either make a new version of the plot or draw the figure anew.

Cheers,

By now you probably know the membership of each individual. Just assign them colors and pass that to the `col` parameter.



library(adegenet)



data(H3N2)

dapc1 <- dapc(H3N2, pop=H3N2$other$epid, n.pca=30,n.da=6)



custom.cols <- sample(c("red", "black"),

                      size = nInd(H3N2),

                      prob = c(0.2, 0.8),

                      replace = TRUE)



scatter(dapc1, col = custom.cols)



Cheers,

Roman

Hello,

I have a scatter plot with 20 groups (using on find.cluster() using 1200 individuals). However I want to use only two color for individuals in same scatter plot with 20 groups.

 

Thanks in advance.

 

Regards,

Roma
