Dear all
In the grep command below, is there a way to identify only "age" and
not "age2"? Thanks.
> x<-c("abc","def","rst","xyz","age","age2")
> x
[1] "abc" "def" "rst" "xyz" "age" "age2"
> grep("age2",x)
[1] 6
> grep("age",x) # I need to grab "age" only, not "age2"
[1] 5 6
Also, I post message to r-help@r-project.org and that's subject to
approval by the list moderator. Am I sending it to the wrong address?
