Your question has already been answered but note that if your data is
a time series and you represent it using zoo it will automatically be
sorted.  Here dates is in reverse chronological order whereas z, the
zoo time series object, is in chronological order:

values <- 13:10
dates <- as.Date("2000-01-01") + 3:0; dates

z <- zoo(values, dates); z
