Percentile

Support functions in R for MMC (mean--mean multiple comparisons) plots.

MMC plots: functions used to interface the simint in R to the MMC functions designed with S-Plus multicomp notation. These are all internal functions that the user doesn't see.

Keywords
dplot
Usage
as.multicomp(x, ...)

as.multicomp.hmtest(x,
                    group="group",
                    focus=x$FNAMES$mainF,
                    ylabel=x$FNAMES$response,
                    lmcall=x$call,
                    means,
                    lmat=t(x$cmatrix),
                    lmat.rows=seq(along=dimnames(lmat)[[1]])[-1],
                    aov.mca,
                    ...)

print.mmc.multicomp(x, ...)

plot.multicomp(x, ...)

as.hmtest(x, ...)

as.hmtest.multicomp(x, eps=.001, ...)
Arguments
x
"hmtest" object for as.multicomp. A "mmc.multicomp" object for print.mmc.multicomp. A "multicomp" object for as.hmtest and plot.multicomp.
...
other arguments.
group
Not currently used
focus
See whichf in simint
ylabel
response variable name on the graph.
lmcall
Not currently used
means
means of the response variable on the focus factor.
lmat, lmat.rows
simint.mmc
aov.mca
"aov" object for the same model formula.
eps
absolute error tolerance as double. See simint.
Value

  • as.multicomp is a generic function to change its argument to a "multicomp" object. as.multicomp.hmtest changes an "hmtest" object to a "multicomp" object. print.mmc.multicomp prints a "mmc.multicomp" object.

Note

The multiple comparisons calculations in R and S-Plus use completely different libraries. MMC plots in R are based on simint. MMC plots in S-Plus are based on multicomp. The MMC plot is the same in both systems. The details of gettting the plot differ.
