position_jitterdodge_ellipse: Jitter points on an ellipse and dodge groups side-to-side

Description

This function dodges groups of points side-to-side and adds elliptical random noise to perfectly over-plotted points. See the position_jitter_ellipse() documentation for more information.

Usage

position_jitterdodge_ellipse(
  jitter.width = NULL,
  jitter.height = NULL,
  dodge.width = 1,
  seed = NA
)

Value

A ggproto object of class PositionJitterdodgeEllipse.

Arguments

jitter.width, jitter.height

The dimensions of the elliptical field, from which over-plotted points are sampled.

dodge.width

The dodging width, which defaults to 1.

seed

A random seed for reproducibility.

  dat <- data.frame(x = rep(1, 500), y = rep(1, 500),
                    group = sample(LETTERS[1:2], 500, replace = TRUE))

  ggplot(dat, aes(x, y, shape = group, color = group)) +
    geom_point(position = position_jitterdodge_ellipse(jitter.width  = 0.5,
                                                       jitter.height =  0.5,
                                                       dodge.width = 1)) +
