make arrowhead from list of bezier control points

Description

make arrowhead from list of bezier control points

Usage

arrow_head_bezier(
  x,
  rotate = 0,
  rescale = c(1, 1),
  nudge = c(0, 0),
  transformations = c("rotater", "rescaler", "nudger"),
  n = 101,
  plot = FALSE,
  show_controls = TRUE
)

Arguments

x	list of control points (as vectors or matrices)
rotate	rotation angle in radians
rescale	a single value or 2-length vector for scaling in x and y
nudge	a single value or 2-length vector for nudging in x and y
transformations	a vector of transformation functions
n	number of points in each bezier curve
plot	plot arrowhead if TRUE
show_controls	show control points if plot = TRUE

Value

a matrix
