KKWa Hi,
KKWa I've been playing with:
joinDate - format(strptime(as.vector(forum[,2]), %d-%b-%y),
KKWa +%d-%b-%Y)
today - format(strptime(as.vector(14-Jun-04),
You have formatted the dates, so you are trying to subtract character
strings.
Convert to Date instead (although you can subtract POSIXlt dates).

Kevin,
[[did you have tough day? usually your Q/A are much
better ;-()]]
Thanks to those who have replied, and yes shame on me..
[I also realised I can just use Sys.Date() to get today's date,
instead
