draw.points {Rgb}

Scatter plot of a track

Description

This function draws a slice of a track content, with a distinct point for each track element.

Usage

  draw.points(slice, start, end, column = "value", pointColor = "#666666",
    cex.lab = 1, cex = 0.6, pch = "+", bty = "o", fg = "#000000", ...)

Arguments

slice

A data.frame holding the data to plot, with elements in rows and data in columns.

start

Single integer value, the left boundary of the window, in base pairs.

end

Single integer value, the right boundary of the window, in base pairs.

column

Single character value, the name of the slice column to use for bar heights.

pointColor

The color to use for points (as a name, an integer or an hexadecimal character description). It can alternatively be a function without argument, which returns a vector of as many colors as slice has rows. It can make direct variable call to any argument described on this page (including custom arguments passed via "...").
