dates() is a great date function in R

[1] 34252 34425 34547 34759 34773
The dates() function makes calendar dates from Julian dates,
>dmp<-dates(ss$MPdate,origin=c(month = 1, day = 1, year = 1900))
> dmp[1:5]
[1] 10/12/93 04/03/94 08/03/94 03/03/95 03/17/95
I would appreciate the comments of more sophi...

m.y=strftime(date,format="%m/%y")
This returns me
