[R] Replacing part of delimited string with R's regex

[arun]

Hi
You could use:
 gsub("([[:alnum:]]+-)([[:alnum:]]+-)(.*)","\\1\\2zzz",name)
#[1] "hsa-miR-zzz" "hsa-miR-zzz" "hsa-let-zzz"
A.K.

Subject: [R] Replacing part of delimited string with R's regex

I have the following list of strings:

name <- c("hsa-miR-555p","hsa-miR-519b-3p","hsa-let-7a")

What I want to do is for each of the above strings
replace the text after second delimiter with "zzz".
Yielding:

hsa-miR-zzz
hsa-miR-zzz
hsa-let-zzz

What's the way to do it?
