Apologies, that should be 
 
grep("[[:digit:]]{2}", x, value=T) returns "pjhj24jhjhd"
 
obviously.

Subject: [R] grep(): returning the matched value



Hi,

I'm looking to use the grep function (or something else) to return the matched pattern as opposed to the whole element. For example:

x <- c("pjhj24jhjhd")
grep("[[:digit:]]{2}", x, value=T) returns "people", whereas I simply want "24". 

Any help would be appreciated,

Thanks, Aidan
