These functions plot correlagrams previously computed with
correlogram.formula.

should a legend be added on the plot?
the level used to discriminate the plotting symbols with colours considering the P-values.
two colours for the plotting symbols: the first one is used

when plotting several correlograms, should they be plotted in trellis-style with lattice (the default), or together on the same plot?

Emmanuel Paradis
When plotting several correlograms with lattice, some options have no
effect: legend, type, and pch (pch=19 is
always used in this situation).
When using pch between 1 and 20 (i.e., non-filled symbols, the
colours specified in col are also used for the lines joining
the points. To keep black lines, it is better to leave pch
between 21 and 25.
