geom_boxjitter: A hybrid boxplot.

Description

Half boxplot, half scatterplot with customizable jitter.

Usage

geom_boxjitter(mapping = NULL, data = NULL, stat = "BoxJitter",
  position = "dodge", ..., outlier.colour = NULL, outlier.color = NULL,
  outlier.fill = NULL, outlier.shape = 19, outlier.size = 1.5,
  outlier.stroke = 0.5, outlier.alpha = NULL, outlier.intersect = FALSE,
  jitter.colour = NULL, jitter.color = NULL, jitter.fill = NULL,
  jitter.shape = 19, jitter.size = 1.5, jitter.stroke = 0.5,
  jitter.alpha = NULL, jitter.width = NULL, jitter.height = NULL,
  jitter.seed = NULL, boxplot.expand = FALSE, notch = FALSE,
  notchwidth = 0.5, varwidth = FALSE, errorbar.draw = FALSE,
  errorbar.length = 0.5, 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), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping.

data

The data to be displayed in this layer. There are three options:

If NULL, the default, the data is inherited from the plot data as specified in the call to ggplot.

A data.frame, or other object, will override the plot data. All objects will be fortified to produce a data frame. See fortify for which variables will be created.

A function will be called with a single argument, the plot data. The return value must be a data.frame., and will be used as the layer data.

stat

Use to override the default connection between geom_boxplot and stat_boxplot.

position

Position adjustment, either as a string, or the result of a call to a position adjustment function.

...

other arguments passed on to layer. These are often aesthetics, used to set an aesthetic to a fixed value, like color = "red" or size = 3. They may also be parameters to the paired geom/stat.

outlier.colour

Default aesthetics for outliers. Set to NULL to inherit from the aesthetics used for the box.

In the unlikely event you specify both US and UK spellings of colour, the US spelling will take precedence.

outlier.color

Default aesthetics for outliers. Set to NULL to inherit from the aesthetics used for the box.

In the unlikely event you specify both US and UK spellings of colour, the US spelling will take precedence.

outlier.fill

Default aesthetics for outliers. Set to NULL to inherit from the aesthetics used for the box.

In the unlikely event you specify both US and UK spellings of colour, the US spelling will take precedence.

outlier.shape

Default aesthetics for outliers. Set to NULL to inherit from the aesthetics used for the box.

In the unlikely event you specify both US and UK spellings of colour, the US spelling will take precedence.

outlier.size

Default aesthetics for outliers. Set to NULL to inherit from the aesthetics used for the box.

In the unlikely event you specify both US and UK spellings of colour, the US spelling will take precedence.

outlier.stroke

Default aesthetics for outliers. Set to NULL to inherit from the aesthetics used for the box.

In the unlikely event you specify both US and UK spellings of colour, the US spelling will take precedence.

outlier.alpha

Default aesthetics for outliers. Set to NULL to inherit from the aesthetics used for the box.

In the unlikely event you specify both US and UK spellings of colour, the US spelling will take precedence.

outlier.intersect

Defaults to `FALSE`. If set to `TRUE`, outliers will be part of the jitter-plot (but keeping the given outlier graphical parameters) rather than plotted vertically above / below the whisker lines.

jitter.colour, jitter.color, jitter.fill, jitter.shape, jitter.size, jitter.stroke, jitter.alpha

Default aesthetics for jitter, set to `NULL` to inherit from the aesthetics used for the box.

jitter.width

Width passed to position_jitter. Defaults to half the width of the boxplot.

jitter.height

Height passed to position_jitter. Defaults to 40 percent of the resolution.

jitter.seed

Seed passed to position_jitter for reproducible jittering.

boxplot.expand

Defaults to `FALSE`. If set to `TRUE`, the full boxplots will be plotted.

notch

if FALSE (default) make a standard box plot. If TRUE, make a notched box plot. Notches are used to compare groups; if the notches of two boxes do not overlap, this suggests that the medians are significantly different.

notchwidth

for a notched box plot, width of the notch relative to the body (default 0.5)

varwidth

if FALSE (default) make a standard box plot. If TRUE, boxes are drawn with widths proportional to the square-roots of the number of observations in the groups (possibly weighted, using the weight aesthetic).

errorbar.draw

Draw horizontal whiskers at the top and bottom (the IQR). Defaults to `FALSE`.

errorbar.length

Length of the horizontal whiskers (errorbar). Defaults to half the width of the half-boxplot, or half the width of the entire boxplot if `boxplot.expand` is set to `TRUE`.

na.rm

If FALSE, the 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

Run this code
# NOT RUN {
set.seed(221)
df <- data.frame(score = rgamma(150, 4, 1), 
                 gender = sample(c("M", "F"), 150, replace = TRUE), 
                 genotype = factor(sample(1:3, 150, replace = TRUE)))

ggplot(df) + geom_boxjitter(aes(x = gender, y = score, fill = genotype),
                            jitter.shape = 21, jitter.color = NA, 
                            jitter.height = 0, jitter.width = 0.04,
                            outlier.color = NA, errorbar.draw = TRUE) +
  scale_fill_manual(values = c("#CF3721", "#31A9B8", "#258039")) +
  theme_minimal()
# }
