In multcompView: Visualizations of Paired Comparisons

#' Summarize multiple paired comparisons
#' 
#' Convert a logical vector or a vector of p-values or a difference or distance
#' matrix into a display identifying the pairs for which the differences were
#' not significantly different or for which the difference exceeded a
#' threshold.

#' \tabular{ll}{ Package: \tab multcompView\cr Type: \tab Package\cr Version:
#' \tab 0.1-0\cr Date: \tab 2006-08-06\cr License: \tab GPL\cr } Convert a
#' logical vector or a vector of p-values or a difference or distance matrix
#' into either a letter-based display using "multcompLetters" or a graphic
#' roughly like a "T" using "multcompTs" to identify factor levels or similar
#' groupings that are or are not significantly different.  Designed for use in
#' conjunction with the output of functions like TukeyHSD, diststats, simint,
#' simtest, csimint, csimtestmultcomp, friedmanmc, kruskalmcpgirmess.
