circos.trackHist

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()
