Convert to polar coordinate system
Convert to polar coordinate system
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.
