In statVisual: Statistical Visualization Tools

Description

Draw stacked bar plots.

Usage

stackedBarPlot(dat, 
	       catVar, 
	       group, 
	       xlab = catVar, 
	       ylab = "Count", 
	       group.lab = group, 
	       title = "Stacked barplots of counts", 
	       catVarLevel = NULL, 
	       groupLevel = NULL, 
	       addThemeFlag = TRUE)

Arguments

dat	A data frame object. Rows are subjects and columns are variables.
catVar	character. The name of the cateogrical variable to be shown in x-axis.

xlab	character. Label for x-axis.
ylab	character. Label for y-axis.
group.lab	character. Label for group in legend.
title	character. Figure title.
catVarLevel	character. A vector indicating the order of the unique elements of catVar should be shown in x-axis.
groupLevel	character. A vector indicating the order of the unique elements of group should be shown in figure and in legend.
addThemeFlag	logical. Indicates if light blue background and white grid should be added to the figure.

pDat = pData(genoSim)
geno = exprs(genoSim)

pDat$snp1 = geno[1,]

stackedBarPlot(dat = pDat, 
	       catVar = "snp1", 
	       group = "grp", 
               xlab = "snp1", 
	       ylab = "Count", 
	       group.lab = "grp",
