arrow_head_catenary {arrowheadr}

Make catenary arrowhead

Description

Make catenary arrowhead

Usage

arrow_head_catenary(
  a = 1,
  base_width = 0,
  thickness = 1.2,
  closed = FALSE,
  rotate = 0,
  rescale = c(1, 1),
  nudge = c(0, 0),
  transformations = c("rotater", "rescaler", "nudger"),
  n = 361,
  plot = FALSE
)

Arguments

a

peakedness of the arch (near 0 is more flat, large like parabola)

base_width

width of the base of the arch

thickness

thickness of the top of the arch

closed

if TRUE, closed arch

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 polygon

plot

plot arrowhead if TRUE

Value

a matrix

    a = 0.4,
    base_width = 0.2,
    thickness = .09
  )
