rotate

R Documentation

Rotates a point (x,y) by an angle

rotate calculates the coordinates for a point (x,y) after it rotates by an angle theta (radian)

rotate(xy, theta = 0)

`xy`	A vector of length 2 representing the coordinates of a point in cartesian system
`theta`	A number rotating angle in radian

Coordinates of the point after the rotation

rotate(c(1000, 0), theta=pi/6)
