transform.shape: Rotate and scale a shape according to parameters

In ash129/penrose: creates the P2 penrose tiling

Description

transform.shape() takes in x coordinates and y coordinates of a point, as well as the penrose's true center. Additional parameters are used to rotate and scale the data.

Usage

## S3 method for class 'shape'
transform(xs, ys, type, core.x = 0, core.y = 0,
  core.rot = 0, core.sca = 1, cent.rot = 0, cent.sca = 1, ticker = 0)

Arguments

xs	numeric vector containing the x coordinates of the points of the shape to be transformed.
ys	numeric vector containing the y coordinates of the points of the shape to be transformed.
core.x	numeric x coordinate of true center of the penrose
core.y	numeric y coordinate of true center of the penrose
core.rot	numeric degrees to rotate the set of all points by, hinged on the true center
core.sca	numeric amount to scale the set of all points by, relative to the true center
cent.rot	numeric degrees to rotate the set of all points by, hinged on the center of points
cent.sca	numeric amount to scale the set of all points by, relative to the center of points
ticker	additional outside parameter for miscellaneous use

Value

list of numeric coordinates for the new shapes from the transform
