[R] cutting out numbers from vectors

[calundergrad]

i have a vector with values similar to the below text
[1] 001-010-001-0

I want to get rid of all leading zeroes.  for example i want to change the
values of the vector so that [1] 001-010-001-0 becomes [1] 1-010-001-0.  

Another example
[1]082-232-232-1 becomes [1] 82-232-232-1

how do i do this?
