For this (and similar cases):
formatC(2108,width=5,flag="0")
# [1] "02108"
For longer strings:
formatC(2108,width=6,flag="0")
# [1] "002108"
see ?formatC for more details (the way formatC() aggregates
information about the desired format is somewhat different
from the format syntax in C's printf() and related functions).
