Extracting Current and Old Date

If I read this correctly:

mydates <- as.Date(c("2007-06-22", "2007-05-21", "2004-04-13",
"2004-03-11","2004-02-13"))
xx  <-  min(mydates)
yy  <-  max(mydates)
yy-xx

#This my look trivial but has been killing my time
#I want to extract most current and old date from mydates #variable that
has more than 10,000 observation.
#Get days
# use as.Date( ) to convert strings to dates
mydates <- as.Date(c("2007-06-22", "2007-05-21", "2004-04-13",
"2004-03-11","2004-02-13",))
#Is there a way/fuction to extract mostcurrent date
#from mydates variable
mostcurrent <- as.Date(c("2007-06-22"))

#Is there a way/function to extract olddate
#from mydates variable
olddate    <- as.Date(c("2004-02-13"))

#Days between most current and old dayte
days <- as.numeric(mostcurrent - olddate)
