R: Draw histogram in cells among a whole track

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(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)

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.
`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()
