PlotCI: Plot Simultaneous Confidence Intervals

In PhilipPallmann/SimLongi: Simultaneous Inference in Longitudinal Data Settings

Description

Draw a plot of simultaneous confidence intervals (SCIs) from multiple comparisons in a longitudinal setting using the ggplot2 framework.

Usage

PlotCI(output, title="95% SCIs", background="white")

Arguments

output	An object of class silo obtained from using functions SimLongi, SimLongiMix, or SimLongiMMM, or a named list of (up to seven) such objects.
title	An optional character string giving the plot title. By default, a standard headline ("95% SCIs") is printed.
background	A character string defining the background color for the plotting region. The default is "white" but may be changed to "gray" for the familiar ggplot2 aesthetics. British spelling ("grey") works as well.

Details

If output is a list containing several objects of class silo, this list must be named (e.g., list(name1=firstobject, name2=secondobject)) so that an informative legend can be created according to the names.

If no headline is desired, simply enter title=NULL.

Value

A graphical display of SCIs.

data(heart)

# Many-to-one comparisons of groups per time point
# taking the third group ("control") as reference

mycomp <- SimLongi(data=heart, response="heartrate", group="drug",
                   time="time", id="person", direction="gpt",
                   type="Dunnett", base=3, df="adj")
      
PlotCI(mycomp)

mycompMMM <- SimLongiMMM(data=heart, response="heartrate", group="drug",
                         time="time", id="person", type="Dunnett", base=3,
                         refdist="t")
                   
PlotCI(list(SL=mycomp, SL_MMM=mycompMMM))
