I am trying to generate a list of length 4n which consists of the integers 1
to n repeated in groups of four, i.e.
1,1,1,1, 2,2,2,2, 3,3,3,3, . . . . , n,n,n,n
(The spaces in the list are added only for clarity.)
I can generate the list as
Look more at help(rep) and help(seq):
n - 7
rep(seq_len(n), each=4)
[1] 1 1 1 1 2 2 2 2 3 3 3 3 4 4 4 4 5 5 5 5 6 6 6 6 7 7 7 7

In '?rep' find out about the 'each' argument.
Also there is the function 'gl' which creates a factor and offers a shorter
syntax for your problem.
If n equals 5 use one of:
rep(seq(5), each = 4)
gl(5,4)

You are not generating lists, you are generating vectors.
Try
rep( seq.int( n ), each= 4 )

Hi, John,
doesn't
n - your number
lapply( 1:n, rep, each = 4)
do what you need?

That would be the each argument to rep()...
n - 5
rep(1:n, each=4)
[1] 1 1 1 1 2 2 2 2 3 3 3 3 4 4 4 4 5 5 5 5
Cheers,

Hi,
You can use the apply group of functions
n-5
k-4
unlist(lapply(1:n,rep, each=k)) # For vector output:
sapply(1:n,rep, each=k) # For a matrix output
Hope this helps
