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

MMC plots: In R, functions used to interface the glht 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
## S3 method for class 'mmc.multicomp':
print(x, ...)

## S3 method for class 'multicomp':
print(x, ...)

## print.multicomp.hh(x, digits = 4, ..., height=T) ## S-Plus only

## S3 method for class 'multicomp.hh':
print(x, ...) ## R only

print.glht.mmc.multicomp(x, ...) ## R.  yes, spell it out.

as.multicomp(x, ...)

## S3 method for class 'glht':
as.multicomp(x,       ## glht object
focus,   ## currently required
ylabel=deparse(terms(x$model)[[2]]), means=model.tables(x$model, type="means",
cterm=focus)$tables[[focus]], height, lmat=t(x$linfct),
lmat.rows=-1,
lmat.scale.abs2=TRUE,
estimate.sign=1,
order.contrasts=TRUE,
contrasts.none=FALSE,
level=0.95,
calpha=NULL,

##### Note

The multiple comparisons calculations in R and S-Plus use completely different libraries. MMC plots in R are based on glht. 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.
