mc_plot {PairViz}R Documentation

Multiple comparison plot.

Description

For grouped data. Draws boxplots for each group and overlays with confidence intervals for pairwise comparison of means.

Usage

mc_plot(data, fit, path = eulerian, col = rainbow(length(data), s = 0.4), levels = c(0.9, 0.95, 0.99), 
cifunction = function(a, level) TukeyHSD(a, conf.level = level)[[1]], 
varwidth = TRUE, frame.plot = FALSE, boxwex = 0.3, cex=0.75, zoom=NULL,ci.yusr=NULL,...)

Arguments

data A list of vectors, such as that returned by split.
fit A fitted model object, usually an aov fit.
path an index vector or a function. If a vector, groups are plotted in order data[path]. By default, it is the function eulerian, and produces an ordering where each pair of groups appears adjacently, with p-values roughly increasing as the sequence progresses.
col A vector of colours, one per group.
levels Vector of increasing confidence levels.
cifunction Function that returns confidence intervals.Default uses TukeyHSD.
varwidth Passed to boxplot.
frame.plot Passed to boxplot.
boxwex Passed to boxplot.
cex Passed to boxplot.
zoom If provided, a numeric vector specifying a subsequence of path to display.
ci.yusr Specifies the vertical par(usr) for the confidence intervals. Defaults to max and min.
... Optional arguments, passed to path and overlayCI.
