Dear experts, For the makeGenotype function I need a list as in the example. However, since my list needs to be 184 long there must be an easy way to make it.>list(1:2,3:4,5:6,7:8)[[1]] [1] 1 2 [[2]] [1] 3 4 [[3]] [1] 5 6 [[4]] [1] 7 8 I have tried lis<-1:184 dim(lis)=c(92,2,1) as.list(lis) and several other options. Any suggestions? many thanks Marco [[alternative HTML version deleted]]
I think there are many simple solutions, here is one: lapply(1:92, function(x) c(2*x-1, 2*x)) Gabor On Tue, Jul 01, 2008 at 02:46:07PM +0200, Boks, M.P.M. wrote:> Dear experts, > > For the makeGenotype function I need a list as in the example.

Use lapply on a costum function. lapply(1:92, function(i){ (i - 1) * 2 + 1:2 }) HTH, Thierry ------------------------------------------------------------------------ ---- ir.
