circos.trackHist: Draw histogram in cells among a whole track

In 1156054203/circlize-: Circular Visualization

Description

Draw histogram in cells among a whole track

Usage

circos.trackHist(factors, x, track.height = circos.par("track.height"),
    track.index = 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)

Arguments

factors	Factors which represent the categories of data
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.
force.ylim	Whether to force all cells in the track to share the same ylim. Btw, ylim is calculated automatically.
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

## Not run: 
x = rnorm(1600)
factors = sample(letters[1:16], 1600, replace = TRUE)
circos.initialize(factors = factors, x = x)
circos.trackHist(factors = factors, x = x, col = "#999999", 
  border = "#999999")
circos.trackHist(factors = factors, x = x, bin.size = 0.1, 
  col = "#999999", border = "#999999")
circos.trackHist(factors = factors, x = x, draw.density = TRUE, 
  col = "#999999", border = "#999999")
circos.clear()

## End(Not run)
