I'm all new to R, assisting the last days of topics from the sideline.
I am, however, a longterm programmer.

This question makes me ask myself - and now here - is there any string
split-function, ex some thing like:

split('/',"2000/3000/4") --> (2000,3000,4)

After this patting with zero is a breeze, sprintf('%010d',...

0le
