Dear R users,
the way I understand the documentation of sub() and regexp the following code:
sub('[[:digit:]]{1,2}', '', '9ewww')
... should yield:
'ewww'
It returns, however:
'www'
Why is this the case? My code should just substitute 1 (minimum) or up to 2
(maximum) digits, i.e. numbers and not the 'e' in the string. Do I misinterpret
something here?
I get your expected output of "ewww" running 2.14.0 or 2.14.0-patched on
Windows. So it's not a universal problem...

Thanks for any ideas
