[adegenet-forum] repooling random rows from genind objects

[Jombart, Thibaut]

What does nrow(F1) and other nrow(...)'s say?

Hello All!

I have three seperate populations as genind objects. What I would like to do is pull a certain number of random individuals from each, to form a new single genind population.

I would then like individuals from this new genind population to mate randomly, producing another genind object which would contain their offspring.

Below is the code I came up with (which does not work):

Year1 <- repool(F1[sample(nrow(F1), 500), ], pop1[sample(nrow(pop1), 750), ], pop2[sample(nrow(pop2), 750), ], n=2000)

Year2 <- hybridize(Year1[sample(nrow(Year1), 1000), ], Year1[sample(nrow(Year1), 1000), ], n=2000)


any help would be greatly appreciated!

Best,
Spencer
