These are enhancements of the Rcmdr Xyplot
function (which I
wrote) to include layout parameters and plot type, to force solid dots, and to
distinguish
between conditioning variables in the formula and group variables.
Xyplot.HH
is an interface to the xyplot
function.
Xyplot.HH2
is an interface to many of the lattice
functions (xyplot
, bwplot
, splom
,
barchart
, dotplot
) and to the formula method for
likert
in the HH
package.
When either barchart
or panel.barchart
is selected, then the argument origin=0
is
automatically set. When panel.barchart
, the user must manually
specify the limits (xlim
or ylim
) to include zero for the effect of origin=0
to
be visible.
