Creating a sequential list of letters with R

I would like to be able to create a sequence of letters in R (to assist in importing data from a SPSS file)

It's quite easy to create a sequence of numbers, for example:

[1] 1 2 3 4 5 6 ... 1000

[1] something1 something2 ... something12

But is there any functionality for appending, pasting, or creating sequences of letters like this?

[1]This_a This_b This_c ... This_4z

Thanks in advance!
