Display degree angles around a unit circle

Display degree angles around a unit circle

Usage

display_degrees(
  x,
  x2 = x,
  add = FALSE,
  col = "darkorange",
  lwd = 2,
  top_degree = 0,
  clockwise = TRUE,
  r1 = 0,
  r2 = 1,
  r0 = 1,
  arrow.length = 0.2,
  xlim = NULL,
  ylim = NULL,
  asp = 1,
  ...
)

Arguments

x

numeric angles in degrees

x2

numeric angles in degrees, optionally used to show when an angle changes from x to x2.

add

logical indicating whether to add to an existing open plot device.

col

character vector of colors recycled to length(x).

lwd

numeric line width.

top_degree

numeric the angle in degrees for the top (12 o'clock) position of the graph.

clockwise

logical indicating whether angles proceed from the top_degree in clockwise (top, top-right, right, bottom-right, bottom, bottom-left, left, top-left, top) or counter-clockwise orientation.

r1, r2

numeric radius values for the start and end position of each arrow vector drawn.

r0

numeric radius used for the axis with labeled angles.

arrow.length

numeric passed to arrows() to define the arrow head length.

xlim, ylim

numeric x-axis and y-axis plot limits, respectively. When not supplied, they automatically use 1.1 times the higher value from c(r1, r2, r0, 1) so that the minimum radius is at at least 1 unless specified otherwise.

...

additional arguments are ignored.
