BioCircosBarTrack {BioCircos}

Create a track with a bar plot to be added to a BioCircos tracklist

Description

Bins are defined by a genomic range and associated with a numerical value

Usage

BioCircosBarTrack(trackname, chromosomes, starts, ends, values,
  labels = "", maxRadius = 0.9, minRadius = 0.5, color = "#40B9D4",
  range = 0, ...)

Arguments

trackname

The name of the new track.

chromosomes

A vector containing the chromosomes on which each bar is found. Values should match the chromosome names given in the genome parameter of the BioCircos function.

starts, ends

Vectors containing the coordinates on which each bin begins or ends.

values

A vector of numerical values associated with each bin, used to determine the height of each bar on the track.

labels

One or multiple character objects to label each bar.

minRadius, maxRadius

Where the track should begin and end, in proportion of the inner radius of the plot.

color

The color for the bars, in hexadecimal RGB format.

range

Vector of values to be mapped to the minimum and maximum radii of the track. Default to 0, mapping the minimal and maximal values input in the values parameter.

BioCircos(BioCircosBarTrack('BarTrack', chromosomes = 1:3, starts = 1e+7*2:4, ends = 2.5e+7*2:4, 
  values = 1:3, labels = c('A ', 'B ', 'C '), range = c(0,4)) + BioCircosBackgroundTrack('BGTrack'))
