Subject: [R] Grep command

Dear all
In the grep command below, is there a way to identify only "age" and not "age2"? In other words, I like to greb "age" and "age2"
separately, one at a time. Thanks.


[1] "abc"  "def"  "rst"  "xyz"  "age"  "age2"


[1] 6

grep("age",x) # I need to grab "age" only, not "age2"

[1] 5 6
