Rotate shapes

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

coo_rotate(x, theta = 0, from_col = coo, to_col = coo, ...)

# S3 method for mom_tbl
coo_rotate(
  x,
  theta = 0,
  from_col = coo,
  to_col = {     {         from_col     } },
  ...
)

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.
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

Methods (by class)

• mom_tbl: mom_tbl method
