I thought it would be quite simple to generate a number of sequences, but my 
only answer is to loop and this doesn't seem in keeping with R's capabilities.

In short I have the start and finish positions of several (well thousands 
probably) sequences. So I am looking at how do I take

x <- c(2,6,13,20)
y <- c(4,10,16,24)

 and produce a list with four components with the appropriate sequence

Something like
[[1]]
[1] 2 3 4

[[2]]
 [1] 6 7 8 9 10

[[3]]
 [1] 13 14 15 16

[[4]]
 [1] 20 21 22 23 24

So can someone point me in the direction of the ******* obvious

See ?seq and ?mapply:

mapply(seq, x, y)
