GraphTrackLine-class: Class "GraphTrackLine"

Description

A UCSC track line for graphical tracks.

Arguments

Objects from the Class

Objects can be created by calls of the form new("GraphTrackLine", ...) or parsed from a character vector track line with as(text, "GraphTrackLine") or converted from a BasicTrackLine using as(basic, "GraphTrackLine").

Slots

altColor:
Object of class "integer" giving an alternate color, as from col2rgb.
autoScale:
Object of class "logical" indicating whether to automatically scale to min/max of the data.
alwaysZero:
Object of class "logical" indicating whether to fix the lower limit of the Y axis at zero.
gridDefault:
Object of class "logical" indicating whether a grid should be drawn.
maxHeightPixels:
Object of class "numeric" of length three (max, default, min), giving the allowable range for the vertical height of the graph.
graphType:
Object of class "character", specifying the graph type, either "bar" or "points".
viewLimits:
Object of class "numeric" and of length two specifying the data range (min, max) shown in the graph.
yLineMark:
Object of class "numeric" giving the position of a horizontal line.
yLineOnOff:
Object of class "logical" indicating whether the yLineMark should be visible.
windowingFunction:
Object of class "character", one of "maximum", "mean", "minimum", for removing points when the graph shrinks.
smoothingWindow:
Object of class "numeric" giving the window size of a smoother to pass over the graph.
type:
Scalar "character" indicating the type of the track, either "wig" or "bedGraph".
name:
Object of class "character" specifying the name of the track.
description:
Object of class "character" describing the track.
visibility:
Object of class "character" indicating the default visible mode of the track, see UCSCTrackModes.
color:
Object of class "integer" representing the track color (as from col2rgb).
priority:
Object of class "numeric" specifying the rank of this track.
