Do transformations in a desired order

Description

Do transformations in a desired order

Usage

transformer(
  x,
  rescale = c(1, 1),
  rotate = 0,
  nudge = 0,
  center = c(0, 0),
  degrees = FALSE,
  transformations = c("unitizer", "rescaler", "nudger", "rotater")
)

Arguments

x	a 2-column matrix
rescale	a single value or a vector with length equal to the number of columns in x
rotate	angle in radians unless degrees is true
nudge	a single value or a vector with length equal to the number of columns in x
center	a single value or a vector with length equal to the number of columns in x
degrees	if TRUE, angles are degrees instead of radians
transformations	a vector of transformation functions

Value

a matrix

Examples

xy <- matrix(c(0,0,1,1), nrow = 2)
transformer(xy, transformations = "rotater", rotate = pi)
