Extracting text from a character string

Shawn Way-2
I have a set of character strings like below:
 
> data3[1]
[1] "CB01_0171_03-27-2002-(Sample 26609)-(126)"
>
 
I am trying to extract the text 03-27-2002 and convert
this into a date for the same record.  I keep looking
at the grep function, however I cannot quite get it to
work.
 
grep("\d\d-\d\d-\d\d\d\d",data3[1],perl=TRUE,value=TRUE)
 
Any hints?
 
Shawn Way
