If you are using R in Unix environment, you can get UUID in R using system() command.

On Linux (Ubuntu 12.04 LTS):

my_uuid <- system("uuid",intern=T)
my_uuid
[1] 0f62f1de-418d-11e3-8a19-cb0ceccb58ec

On Mac OS X 10.8:

my_uuid <- system("uuidgen", intern=T)
my_uuid
[1] 9A9D64DF-EB01-47E7-B16E-DC0343951883

Far as I know, both uuid and uuidgen follows UUID Version 4 format.
