imagine the following data.frame:

ID name
1 *_A
2 *_A
3 *_B
4 *_B

* = can be any pattern

I want to replace every row which ends with _A by 1 and every row which ends
by _B with a 0

so that the data.frame looks like the following:

ID name
1 1
2 1
3 0
4 0

Which function do I use best to achieve this?
