ggborderlines extensions to ggplot2

Description

ggborderlines makes use of the ggproto class system to extend the functionality of ggplot2. In general the actual classes should be of little interest to users as the standard ggplot2 api of using geom_* and stat_* functions for building up the plot is encouraged.

Usage

GeomBorderpath

GeomBorderline

GeomBorderstep

Format

An object of class GeomBorderpath (inherits from GeomPath, Geom, ggproto, gg) of length 7.

An object of class GeomBorderline (inherits from GeomBorderpath, GeomPath, Geom, ggproto, gg) of length 4.

An object of class GeomBorderstep (inherits from GeomBorderpath, GeomPath, Geom, ggproto, gg) of length 2.

Key glyphs for legends

Description

Key glyphs for legends

Usage

draw_key_borderpath(data, params, size)

Arguments

data, params, size

See ggplot2::draw_key_path() for usage

Value

A gTree object

Connect observations

Description

This set of geoms is very similar to ggplot2::geom_path(), ggplot2::geom_line() and ggplot2::geom_step(), with the only difference being that they accept two additional aesthetics, bordercolour and borderwidth. For additional documentation, please refer to the ggplot2 geoms.

Usage

geom_borderpath(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  lineend = "butt",
  linejoin = "round",
  linemitre = 10,
  arrow = NULL,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

geom_borderline(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  lineend = "butt",
  linejoin = "round",
  linemitre = 10,
  arrow = NULL,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

geom_borderstep(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  direction = "hv",
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE,
  ...
)

Arguments

mapping

Set of aesthetic mappings created by 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. A function can be created from a formula (e.g. ~ head(.x, 10)).

stat

The statistical transformation to use on the data for this layer. When using a ⁠geom_*()⁠ function to construct a layer, the stat argument can be used the override the default coupling between geoms and stats. The stat argument accepts the following:

  • A Stat ggproto subclass, for example StatCount.

  • A string naming the stat. To give the stat as a string, strip the function name of the stat_ prefix. For example, to use stat_count(), give the stat as "count".

  • For more information and other ways to specify the stat, see the layer stat documentation.

position

A position adjustment to use on the data for this layer. This can be used in various ways, including to prevent overplotting and improving the display. The position argument accepts the following:

  • The result of calling a position function, such as position_jitter(). This method allows for passing extra arguments to the position.

  • A string naming the position adjustment. To give the position as a string, strip the function name of the position_ prefix. For example, to use position_jitter(), give the position as "jitter".

  • For more information and other ways to specify the position, see the layer position documentation.

...

Other arguments passed on to layer()'s params argument. These arguments broadly fall into one of 4 categories below. Notably, further arguments to the position argument, or aesthetics that are required can not be passed through .... Unknown arguments that are not part of the 4 categories below are ignored.

  • Static aesthetics that are not mapped to a scale, but are at a fixed value and apply to the layer as a whole. For example, colour = "red" or linewidth = 3. The geom's documentation has an Aesthetics section that lists the available options. The 'required' aesthetics cannot be passed on to the params. Please note that while passing unmapped aesthetics as vectors is technically possible, the order and required length is not guaranteed to be parallel to the input data.

  • When constructing a layer using a ⁠stat_*()⁠ function, the ... argument can be used to pass on parameters to the geom part of the layer. An example of this is stat_density(geom = "area", outline.type = "both"). The geom's documentation lists which parameters it can accept.

  • Inversely, when constructing a layer using a ⁠geom_*()⁠ function, the ... argument can be used to pass on parameters to the stat part of the layer. An example of this is geom_area(stat = "density", adjust = 0.5). The stat's documentation lists which parameters it can accept.

  • The key_glyph argument of layer() may also be passed on through .... This can be one of the functions described as key glyphs, to change the display of the layer in the legend.

lineend

Line end style (round, butt, square).

linejoin

Line join style (round, mitre, bevel).

linemitre

Line mitre limit (number greater than 1).

arrow

Arrow specification, as created by grid::arrow().

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. borders().

direction

direction of stairs: 'vh' for vertical then horizontal, 'hv' for horizontal then vertical, or 'mid' for step half-way between adjacent x-values.

Value

A ggproto layer object

Examples

require(ggplot2)

# geom_borderline() adds a border around lines
ggplot(economics_long, aes(date, value01, colour = variable)) +
  geom_borderline()

# You can control the linewidth and colour of the border with the
# borderwidth and bordercolour aesthetics:
ggplot(economics_long, aes(date, value01, bordercolour = variable)) +
  geom_borderline(borderwidth = .4, colour = "white")

# The background 'border' part of the geom is always solid, however this
# can be used to create some nice effects:
x <- seq(0, 4 * pi, length.out = 500)
test_data <- data.frame(
  x = rep(x, 2), y = c(sin(x), cos(x)),
  fun = rep(c("sin", "cos"), each = 500)
)
ggplot(test_data, aes(x, y, colour = fun)) +
  geom_borderline(linewidth = 1, linetype = "dashed", lineend = "round")

Scales for borderlines

Description

These scales control the linewidth and colour of the borders in borderlines. They work in much the same way as ggplot2::scale_colour_continuous(), ggplot2::scale_linewidth_discrete(), etc.

Usage

scale_bordercolour_continuous(..., aesthetics = "bordercolour")

scale_bordercolour_discrete(..., aesthetics = "bordercolour")

scale_borderwidth_continuous(..., aesthetics = "borderwidth")

scale_borderwidth_discrete(..., aesthetics = "borderwidth")

Arguments

...

Passed to the corresponding ggplot2 scales

aesthetics

Character string or vector of character strings listing the name(s) of the aesthetic(s) that this scale works with. This can be useful, for example, to apply colour settings to the bordercolour and colour aesthetics at the same time, via aesthetics = c("bordercolour", "colour").

Value

A ggproto scale object
