question about string handling....
Hi,
I have a data.frame as following:
var1 var2
1 ab_c_(ok)
2 okf789(db)_c
3 jojfiod(90).gt
4 "ij"_(78)__op
5 (iojfodjfo)_ab
what I want is to create a new variable called "var3". the value of var3 is
the content in the Parentheses. so var3 would be:
var3
ok
db
90
78
iojfodjfo
how to do this?
thanks,
karena
