I have a data from with 3 numeric variables, and wish to create a Date object. The old "date" library had a function mdy.date to do this. I've chased all of the See Also sections I can find for the Date class, and didn't find anything comparable. Yes, I can use as.Date(paste(data$year+1900, data$month, data$day), sep='/')) but it seems odd pack something together that will immediately be unpacked. Terry Therneau

I would use paste but as.Date(ISOdate(...)) is another possibility although it uses paste internally itself.
