Couple of choices depending on what you want to do with the data:
> x <- as.POSIXct("05/16/2008", format="%m/%d/%Y")  #
if you want to use the
date
> format(x, "%d") # day
[1] "16"
> format(x, "%m") # month
[1] "05"
> format(x, "%Y") # year
[1] "2008"
> # or
> y <- strsplit("05/16/2008", '/')  # to just get the
characters
> y
[[1]]
[1] "05"   "16"   "2008"

There are many ways to do this in R.  See R News 4/1 for info on dates.
Here is one method:
> library(chron)
> mdy <- month.day.year("05/16/2008")
> mdy
$month
[1] 5

$day
[1] 16

$year
[1] 2008
> mdy$month
[1] 5
