# autotrack: autotrack In karyoploteR: Plot customizable linear genomes displaying arbitrary data

## Description

Computes r0 and r1 given track definition

## Usage

 `1` ```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

 ``` 1 2 3 4 5 6 7 8 9 10 11 12``` ```#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) ```
