rotate_coords {sportyR} | R Documentation |
Perform a mathematical rotation about (0, 0) of coordinates. This rotation is given as x' = x \* cos(theta) - y \* sin(theta) y' = x \* sin(theta) + y \* cos(theta)
Description
Perform a mathematical rotation about (0, 0) of coordinates. This rotation is given as x' = x \* cos(theta) - y \* sin(theta) y' = x \* sin(theta) + y \* cos(theta)
