Description

Make pie chart and bar plot based on the given data frame.

Usage

chartPlots(x, chartType = c("pieChart", "barPlot", "all"), specifiedCols = c("genes in Category"), top = 5, newWindow=TRUE, ...)

Arguments

x

a data frame to be used for pie chart and box plot

chartType

plot type, "pieChart", "barPlot" or both could be specified.

specifiedCols

the column will be used to be represented.

top

number to specify how many first categories will be drawn.

newWindow

logic, determine whether draw on a new canvas.

...

additional arguments passed to piechart or barplot.

Examples

x <- matrix(c(6,9,3,30,13,2,15,20), nrow = 4, ncol=2, byrow=FALSE,
               dimnames = list(c("group1", "group2", "group3", "group4"),
                               c("value1", "value2")))
chartPlots(x, chartType='all', specifiedCol = "value2", top = 3)
