I tried a few things with the date package and this is one of the result I

xd<-c("19-May-00", "22-May-00", "23-May-00", "24-May-00", "25-May-00")

xd<-c("19-May-2000", "22-May-2000", "23-May-2000", "24-May-2000",
[1] 19May2000 22May2000 23May2000 24May2000 25May2000

Any suggestion on how to word around this little problem? Note that this is
a small sample, I would not like to have to do these corrections to hundreds
of dates manualy.

Thanks in advance
