rescale_coordinates | R Documentation |
Returns a list containing 2 functions to translate x and y coordinates, from one set of pitch dimensions (i.e. data provider) to another.
Any x or y coordinate is rescaled linearly between the nearest two pitch markings. For example, the edge of the penalty box and the half way-line.
