You can also use colsplit from reshape2 to split your vector into character and digit columns in one step:

library(reshape2)

colsplit(my.data, "(?<=\\p{L})(?=[\\d+$])", c("char", "digit"))

Result:

  char digit
1  aaa    NA
2    b    11
3    b    21
4    b   101
5    b   111
6  ccc     1
7  ffffd     1
8  ccc    20
9  ffffd    13

Data:

my.data <- c("aaa", "b11", "b21", "b101", "b111", "ccc1", "ffffd1", "ccc20", "ffffd13")
