spin a SpatVector
Spin (rotate) the geometry of a SpatVector.
## S4 method for signature 'SpatVector' spin(x, angle, x0, y0)
x |
SpatVector |
angle |
numeric. Angle of rotation in degrees |
x0 |
numeric. x-coordinate of the center of rotation. If missing, the center of the extent of |
y0 |
numeric. y-coordinate of the center of rotation. If missing, the center of the extent of |
