In bernatgel/karyoploteR: Plot customizable linear genomes displaying arbitrary data

autotrack

Description

Computes r0 and r1 given track definition

Usage

autotrack(current.track, total.tracks, margin=0.05, r0=0, r1=1)

Arguments

current.track	(numeric) The track or tracks the current plot will occupy, starting from 1. If more than one value is provided, the plot will expand from min(current.track) to max(current.track).
total.tracks	(numeric) The total number of tracks
margin	(numeric) The margin is specified as the part of a track, by default 0.05, 5 percent of the track height.
r0	(numeric) the original r0
r1	(numeric) the original r1

Details

Small utility function to help compute r0 and r1 given the total number of tracks and the track(s) the current plot will occupy. It also takes into account a margin between tracks and original r0 and r1, so we can say something like, "Out of 5 tracks between 0 and 0.5, this plot will be at track 2", and it will return r0=0.1 and r1=0.2

Value

A list of two numerics: r0 and r1

Examples

#first track out of 4  
autotrack(1, 4)

#the same, but without margin
autotrack(1, 4, 0)

#first and second tracks out of 4
autotrack(c(1,2), 4)

#The first track out of 4, fitting the four track between 0 and 0.5
autotrack(1, 4, r0=0, r1=0.5)
