Convert data coordinates to polar coordinates — xy_to_polar • spiralize

Convert data coordinates to polar coordinates

xy_to_polar(x, y, track_index = current_track_index(), flip = TRUE)

Arguments

x: X-locations of the data points.
y: Y-locations of the data points.
track_index: Index of the track.
flip: If it is FALSE, it returns theta for the original spiral (before flipping).

Details

Note different settings of flip and reverse in spiral_initialize affect the conversion.

Value

A data frame with two columns: theta (in radians) and r (the radius).
