Default Panel Function for ci.plot
Find or assign the implied position for graphing the levels of a
factor.
A new class "positioned", which inherits from "ordered" and "factor",
is defined.
Initializing Trellis Displays
Support functions in R for MMC (mean--mean multiple comparisons) plots.
Class "positioned", extends "ordered" to specify the position
for graphing the levels of a factor.
Force all comparisons in a "multicomp" object to have the same sign.
partial correlations
Residual plots for a linear model.
scatterplot matrix with potentially different sets of variables
on the rows and columns.
Function based on S-Plus panel.pairs to add the subpanel.scales
and panel.cex arguments.
Homogeneity of Variance Plot

MMC (mean--mean multiple comparisons) plots.
Update a multicomp object by ordering its contrasts.
Interaction plot, with an option to print standard error bars.
Replacement for bwplot.formula and compute.packet in R to allow them
to work with the new "positioned" class.
plot x and y,
with optional straight line fit and display of squared residuals
