circlize: Convert to polar coordinate system

In 1156054203/circlize-: Circular Visualization

Description

Convert to polar coordinate system

Usage

circlize(x, y, sector.index = get.current.sector.index(),
    track.index = get.current.track.index())

Arguments

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

Details

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.

Value

A matrix with two columns (theta and rou). rou is measured in degree.

Examples

pdf(NULL)
factors = c("a", "b")
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)
circos.clear()
dev.off()
