characters in a string
Hi,
I need to check if a string "<rh>a,b,c,d<rh>" is delimited by two "<rh>" 's as efficiently as possible(I need to do this a lot of times) and return TRUE. Can someone suggest a good technique?

get absolute file path
Hello,
I get a value which stores a relative file name. (I get it from another
function, which I don't want to change.)
e.g.
> fileName <- "../data/2010-08.csv";

Kind regards,
Sebastian
