Rotate
Description
Rotate 2D and complex-valued observations. The output is of the same kind as the input.
Usage
rotate (xy, angle, degrees = FALSE, origin = TRUE)
Arguments
xy |
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. |
origin |
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). |

Examples
## rotate points in a 2D space
#mat = cbind (1:100, 100:1)
#rotate (mat, pi/2)
## rotate complex-valued numbers
#complx = complex (real = mat[,1], imaginary = mat[,2])
#rotate (complx, pi/2)
