Create series of circles labels text

Source: R/geom-series-circles.R
geom_series_text.Rd

geom_series_text is designed to be used in concert with geom_series_circles. It renders the label mapping to the final position of the series of circles sequence.

There are three arguments absolutely needed in aes() mappings:

  • x A vector mapping the abscissa axis x, i.e. a character vector when x is a numerical vector, or a numerical vector when y is a character vector.

  • y A vector mapping the ordinate axis y, i.e. a numerical vector when x is a character vector or vice versa.

  • label Labels.

Usage

GeomSeriesText

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

Format

An object of class GeomSeriesText (inherits from GeomText, Geom, ggproto, gg) of length 1.

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)).

position

Position adjustment, either as a string, or the result of a call to a position adjustment function. Cannot be jointly specified with nudge_x or nudge_y.

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.

na.rm

If FALSE, the default, missing values are removed with a warning. If TRUE, missing values are silently removed.

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().

...

Other arguments passed on to 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.

Value

A ggplot2 layer.

Examples

my_df <- data.frame(cat = c("Apple", "Banana", "Pineapple"), val = c(2.65, 4.5, 6.25))
my_df |>
  ggplot2::ggplot() +
  geom_series_circles(ggplot2::aes(cat, val)) +
  geom_series_text(ggplot2::aes(cat, val, label = cat)) +
  ggplot2::coord_equal()
