Description

xPieplot is supposed to visualise data frame using pie plots. It returns an object of class "ggplot".

xPieplot(df, columns, colormap = "ggplot2", pie.radius = NULL,
pie.color = "transparent", pie.color.alpha = 1, pie.thick = 0.1,
legend.title = "", gp = NULL)

Arguments

df

a data frame

columns

a vector containing column names of the input data frame. These columns are used to draw pie charts

colormap

short name for the colormap. It can be one of "jet" (jet colormap), "bwr" (blue-white-red colormap), "gbr" (green-black-red colormap), "wyr" (white-yellow-red colormap), "br" (black-red colormap), "yr" (yellow-red colormap), "wb" (white-black colormap), "rainbow" (rainbow colormap, that is, red-yellow-green-cyan-blue-magenta), and "ggplot2" (emulating ggplot2 default color palette).
