Either, a vector of complex-valued observations, or a matrix with 2 columns and any number of rows.
angle
The desired angle of rotation, in radians.
degrees
If angle of rotation is specified in degrees instead of radians, this should be set to TRUE.

If TRUE, points are rotated about the origin. If FALSE, points are rotated 'in place' about the mean for each dimension (i.e. the central location of the distribution).
