R help - Feb 2005 - gl and different number of replications

I am trying to use the function gl (generate levels), and would like to make 
levels with different number of replications. Does anyone know how to 
generate different number of replications in each level?

Something like:

[1] Site1 Site1 Site1 Site1 Site1 Site1 Site1
[8] Site2 Site2 Site2 Site2 Site2

Thanks in advance

Can't do it. gl is based on rep(), which  easily does what you want:

factor(rep(c('Site1','Site2'),c(7,5)))
