Rotate shapes and specify center

Rotates the coordinates by a theta angle (in radians) in the trigonometric direction (anti-clockwise) and using center as coordinates.

coo_rotatecenter(
  x,
  theta = 0,
  center = c(0, 0),
  from_col = coo,
  to_col = coo,
  ...
)

Arguments

x	coo_single, coo_list or mom_tbl
theta	numeric angle to rotate (in radians) and in the trigonometric direction (anti-clockwise). Default to 0.
center	numeric of length 2, sepcifying the (x; y) coordinates of the rotation center. Default to c(0, 0)
from_col	colnames from where to get the coo_list and how to name the resulting one (only for mom_tbl method)
to_col	colnames from where to get the coo_list and how to name the resulting one (only for mom_tbl method)
...	useless here

Value

a coo_single, coo_list or mom_tbl
