Use lapply on a costum function.

lapply(1:92, function(i){
    (i - 1) * 2 + 1:2
})

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.
~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.
~ Roger Brinner

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.

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
