MMC (Mean-mean Multiple Comparisons) plots in lattice.

Description

MMC (Mean–mean Multiple Comparisons) plots in lattice

Usage

mmcplot(mmc, ...)
## S3 method for class 'mmc'
mmcplot(mmc, col=c("black","red"), lwd=c(1,1), lty=c(2,1), ...,
                  style=c("isomeans", "confint", "both"),
                  type=c("mca", "lmat", "linfct", "none"))
## S3 method for class 'glht'
mmcplot(mmc, col=c("black","red"), lwd=c(1,1), lty=c(2,1),
                  focus=mmc$focus, ...)
## S3 method for class 'mmc.multicomp'
mmcplot(mmc, col=c("black","red"), lwd=c(1,1), lty=c(2,1), ...)
## S3 method for class 'multicomp'
mmcplot(mmc, col=c("black","red"), lwd=c(1,1), lty=c(2,1), ...)
## Default S3 method:
mmcplot(mmc, ...)

Arguments

mmc	mmc object or other object as indicated by method.
col, lwd, lty	Standard xyplot arguments applied to the line segments representing the contrasts.
focus	Name of the factor for which the glht object was constructed.
...	Other arguments to be passed on to the functions called by the methods.
style	Style of graph: The default isomeans is the standard MMC plot with the isomeans grid. confint is a confidence interval plot, similar to the plot produced by multcomp:::plot.glht. both prints both the isomeans and the confint plot as two panels of a trellis structure. When the underlying sets of means are close to each other, there will of necessity be overprinting in the isomeans panel and the confint panel will be needed as a tiebreaker. By default the xlim for the confint style will match the xlim of the corresponding isomeans plot.
type	mca for the default paired-comparisons plot. lmat or linfct for a user-specified set of contrasts. none for confidence intervals on the set of group means (that is, no comparisons).

Value

A trellis object containing the graphs.

Examples

catalystm1.aov <- aov(concent ~ catalyst, data=catalystm)
catalystm.mmc <-
   mmc(catalystm1.aov, linfct = mcp(catalyst = "Tukey"))
mmcplot(catalystm.mmc)
mmcplot(catalystm.mmc, style="both", MMCname="catalyst")
