Subject: code patterns in vector
Dear List,
I have this column/vector:
vec <- c("function", "missing", "string")
and want to compute a second column/vector:
- value if the pattern "unc" is found: 1
- value if the pattern "iss" is found: 2
- value if none of the patterns is found: 0
This should be the result:
> vec2
[1] 1 2 0
Any help? Tried it with grep, but the output is not as long as vec, so
I'm lost a bit here.
Thanks,
Stefan
