circos.trackHist {circlize}R Documentation

Draw histogram in cells among a whole track

Description

Draw histogram in cells among a whole track

Usage

circos.trackHist(
    sectors,
    x,
    track.height = circos.par("track.height"),
    track.index = NULL,
    ylim = NULL,
    force.ylim = TRUE,
    col = ifelse(draw.density, "black", NA),
    border = "black",
    lty = par("lty"),
    lwd = par("lwd"),
    bg.col = NA,
    bg.border = "black",
    bg.lty = par("lty"),
    bg.lwd = par("lwd"),
    breaks = "Sturges",
    include.lowest = TRUE,
    right = TRUE,
    draw.density = FALSE,
    bin.size = NULL,
    area = FALSE,
    factors = sectors)

Arguments

sectors

A factor or a character vector which represents the categories of data

factors

The same as sectors. It will be removed in future versions.

x

Data on the x-axis

track.index

Index for the track which is going to be updated. Setting it to NULL means creating the plotting regions in the next newest track.

track.height

Height of the track. It is the percentage to the radius of the unit circle. If to update a track, this argument is disabled.

ylim

Ranges on y-direction. By default, ylim is calculated automatically.

force.ylim

Whether to force all cells in the track to share the same ylim.

col

Filled color for histogram

border

Border color for histogram

lty

Line style for histogram

lwd

Line width for histogram

bg.col

Background color for the plotting regions

bg.border

Color for the border of the plotting regions

bg.lty

Line style for the border of the plotting regions

bg.lwd

Line width for the border of the plotting regions

breaks

see hist

include.lowest

see hist

right

see hist

draw.density

whether draw density lines instead of histogram bars.

area

whether to fill the area below the density lines. If it is set to TRUE, col controls the filled color in the area and border controls color of the line.

bin.size

size of the bins of the histogram

Details

It draw histogram in cells among a whole track. It is also an example to show how to add self-defined high-level graphics by this package.

Examples


x = rnorm(1600)
sectors = sample(letters[1:16], 1600, replace = TRUE)
circos.initialize(sectors, x = x)
circos.trackHist(sectors, x = x, col = "#999999",
  border = "#999999")
circos.trackHist(sectors, x = x, bin.size = 0.1,
  col = "#999999", border = "#999999")
circos.trackHist(sectors, x = x, draw.density = TRUE,
  col = "#999999", border = "#999999")
circos.clear()
