In XGR: Exploring Genomic Relations for Enhanced Interpretation Through Enrichment, Similarity, Network and Annotation Analysis

Description

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

Usage

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). Alternatively, any hyphen-separated HTML color names, e.g. "lightyellow-orange" (by default), "blue-black-yellow", "royalblue-white-sandybrown", "darkgreen-white-darkviolet". A list of standard color names can be found in http://html-color-codes.info/color-names
pie.radius	the radius of a pie. If NULL, it equals roughly 1/75
pie.color	the border color of a pie
pie.color.alpha	the 0-1 value specifying transparency of pie border colors
pie.thick	the pie border thickness
legend.title	the legend title
gp	an existing ggplot object or NULL. It is used for overlapping

Value
