Hi Jason,
You aren't converting the date to something else, just displaying it as 
a character vector by using the format function. Whenever you form a 
vector, R tries to convert everything in it to the same data type. If 
you _assign_ that vector to something else:

mymax<-c(MaxUpdated_row, as.Date(MaxUpdated_val, "%Y-%m-%d""))

you will have the date type in the MaxUpdated_val and the character type 
in mymax.
