Add Points to a Circular Plot

Description

Add points to a plot of circular data points on the current graphics device.

Usage

plot_points(
  x,
  axial = TRUE,
  stack = FALSE,
  binwidth = 1,
  cex = 1,
  sep = 0.025,
  jitter_factor = 0,
  ...,
  scale = 1.1,
  add = TRUE,
  main = NULL,
  labels = TRUE,
  at = seq(0, 360 - 45, 45),
  cborder = TRUE
)

Arguments

x	Data to be plotted. A numeric vector containing angles (in degrees).
axial	Logical. Whether data are uniaxial (axial=FALSE) or biaxial (TRUE, the default).
stack	logical: if TRUE, points are stacked on the perimeter of the circle. Otherwise, all points are plotted on the perimeter of the circle. Default is FALSE.
binwidth	numeric. Bin width (in degrees) for the stacked dot plots. ignored when stack==FALSE. Is set to 1 degree by default.
cex	character (or symbol) expansion: a numerical vector. This works as a multiple of par("cex").
sep	constant used to specify the distance between stacked points, if stack==TRUE or in the case of more than one dataset. Default is 0.025; smaller values will create smaller spaces.
jitter_factor	numeric. Adds a small amount of random variation to the location of each points along radius that is added to scale. Jitter is ignored when stack==TRUE). If 0, no jitter is added (by default); if negative, the points fall into the circle.
...	Further graphical parameters may also be supplied as arguments.
scale	radius of plotted circle. Default is 1.1. Larger values shrink the circle, while smaller values enlarge the circle.
add	logical
main	Character string specifying the title of the plot.
labels	Either a logical value indicating whether to plot labels next to the tick marks, or a vector of labels for the tick marks.
at	Optional vector of angles at which tick marks should be plotted. Set at=numeric(0) to suppress tick marks.
cborder	logical. Border of rose plot.

Value

A list with information on the plot

Examples

x <- rvm(100, mean = 90, k = 5)
plot_points(x, add = FALSE)
plot_points(x, jitter_factor = .2, add = FALSE) # jittered plot
plot_points(x, stack = TRUE, binwidth = 3, add = FALSE) # stacked plot
