geom_quasirandom: Points, jittered to reduce overplotting using the vipor package

Description

The quasirandom geom is a convenient means to offset points within categories to reduce overplotting. Uses the vipor package.

Usage

geom_quasirandom(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  ...,
  method = "quasirandom",
  width = NULL,
  varwidth = FALSE,
  bandwidth = 0.5,
  nbins = NULL,
  dodge.width = NULL,
  groupOnX = NULL,
  orientation = NULL,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

Arguments

mapping

Set of aesthetic mappings created by aes or aes_. If specified and inherit.aes = TRUE (the default), is combined with the default mapping at the top level of the plot. You only need to supply mapping if there isn't a mapping defined for the plot.

data

A data frame. If specified, overrides the default data frame defined at the top level of the plot.

stat

The statistical transformation to use on the data for this layer, as a string.

...

other arguments passed to ggplot2::layer params argument.

method

Method used for distributing points. Options are "quasirandom" (default), "pseudorandom", "smiley", "maxout", "frowney", "minout", "tukey", "tukeyDense". See vipor::offsetSingleGroup() for the details of each method.

width

Maximum amount of spread (default: 0.4)

varwidth

Vary the width by the relative size of each group. (default: FALSE)

bandwidth

the bandwidth adjustment to use when calculating density Smaller numbers (< 1) produce a tighter "fit". (default: 0.5)

nbins

the number of bins used when calculating density (has little effect with quasirandom/random distribution)

dodge.width

Amount by which points from different aesthetic groups will be dodged. This requires that one of the aesthetics is a factor. To disable dodging between groups, set this to NULL. (default: 0)

groupOnX

See orientation.

orientation

The orientation (i.e., which axis to group on) is inferred from the data. This can be overridden by setting orientation to either "x" or "y".

na.rm

if FALSE (default), missing values are removed with a warning. If TRUE, missing values are silently removed.

show.legend

logical. Should this layer be included in the legends? NA, the default, includes if any aesthetics are mapped. FALSE never includes, and TRUE always includes.

inherit.aes

If FALSE, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g. borders.

Examples

  # Generate fake data
  distro <- data.frame(
    'variable'=rep(c('runif','rnorm'),each=100),
    'value'=c(runif(100, min=-3, max=3), rnorm(100))
  )
  ggplot2::ggplot(distro, ggplot2::aes(variable, value)) + 
  geom_quasirandom(width=0.1)
