Convert to polar coordinate system

1 2 | ```
circlize(x, y, sector.index = get.current.sector.index(),
track.index = get.current.track.index())
``` |

`x` |
Data points on x-axis. The value can also be a two-column matrix/data frame if you put x and y data points into one variable. |

`y` |
Data points on y-axis. |

`sector.index` |
Index for the sector to convert the coordinates |

`track.index` |
Index for the track to convert the coordinates |

This is the core function in the package. It transform data points from data coordinate system (in a specific cell) to the polar coordinate system.

A matrix with two columns (`theta`

and `rou`

). `rou`

is measured in degree.

circos.initialize(factors, xlim = c(0, 1))
circos.track(ylim = c(0, 1))
# x = 0.5, y = 0.5 in sector a and track 1
circlize(0.5, 0.5, sector.index = "a", track.index = 1)
