When issuing the command "acf(ts.union(mdeaths, fdeaths))", the plot.acf()
function plots the negative lags of the autocorrelation values for mdeaths and
fdeaths in the lower left-hand corner of the graphics window, but plot.acf()
labels this graph as "fdeaths & mdeaths" (instead of "mdeaths & fdeaths").  The
order of the variables does matter for the autocorrelation function.
