Thanks Henrique.
This is indeed short and quite simple compared to what I was using which
goes like...
unlist(strsplit(i,split=" "))[grep("ENSP",unlist(strsplit(i,split=" ")))]

Cheers,

string.
Try this:
sapply(strsplit(i, ' '), grep, pattern='ENSP', value = T)

Hi,
Is there a way in R to get the string which matches the expression, where
the expression is a substring of the parent string.
Lets say, I have $i <- "transcript:ENST0000112334 pid:ENSP000012345"
What I need is the string "pid:ENSP000012345" from $i using the query
"ENSP".
Appreciate your comments.
