geom_bar_rounded: Bar plot with rounded corners

Description

Create a bar plot with rounded corners using 'ggplot2'. geom_col_rounded() and geom_bar_rounded() are extensions of the ggplot2::geom_col() and ggplot2::geom_bar() functions and they provide additional aesthetics for more visually appealing outputs.

Usage

geom_bar_rounded(
  mapping = NULL,
  data = NULL,
  position = ggplot2::position_stack(reverse = TRUE),
  radius = grid::unit(4, "pt"),
  ...,
  width = NULL,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)
geom_col_rounded(
  mapping = NULL,
  data = NULL,
  position = ggplot2::position_stack(reverse = TRUE),
  radius = grid::unit(4, "pt"),
  ...,
  width = NULL,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

Value

A ggplot object.

Arguments

mapping

Set of aesthetic mappings created by ggplot2::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 ggplot2::ggplot().

A data.frame, or other object, will override the plot data. All objects will be fortified to produce a data frame. See ggplot2::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. A function can be created from a formula (e.g. ~ head(.x, 10)).

position

Position adjustment, either as a string naming the adjustment (e.g. "jitter" to use position_jitter), or the result of a call to a position adjustment function. Use the latter if you need to change the settings of the adjustment.

radius

The radius of the rounded corners, given as a unit object.

...

Other arguments passed on to ggplot2::layer(). These are often aesthetics, used to set an aesthetic to a fixed value, like colour = "red" or size = 3. They may also be parameters to the paired geom/stat.

width

Bar width. If not supplied, the default is to use the width of 90% of the resolution of the data.

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. It can also be a named logical vector to finely select the aesthetics to display.

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. ggplot2::borders().

Examples

library(ggplot2)

ggplot(data.frame(x = letters[1:3], y = c(2.3, 1.9, 3.2)), aes(x, y)) +
  geom_col_rounded()

ggplot(mpg, aes(class)) +
  geom_bar_rounded()
