Interactive raster plots

Source: R/ggiraph-documentation-with-examples.R
gf_raster_interactive.Rd

Creates an interactive plot using ggiraph. This function extends gf_raster() with interactive features like tooltips and clickable elements.

Usage

gf_raster_interactive(
  object = NULL,
  gformula = NULL,
  data = NULL,
  ...,
  alpha,
  color,
  fill,
  group,
  linetype,
  linewidth,
  hjust = 0.5,
  vjust = 0.5,
  interpolate = FALSE,
  xlab,
  ylab,
  title,
  subtitle,
  caption,
  stat = "identity",
  position = "identity",
  show.legend = NA,
  show.help = NULL,
  inherit = TRUE,
  environment = parent.frame()
)

Arguments

object

When chaining, this holds an object produced in the earlier portions of the chain. Most users can safely ignore this argument. See details and examples.

gformula

A formula with shape y ~ x or fill ~ x + y

data

A data frame with the variables to be plotted.

...

Additional arguments passed to the underlying interactive geom. This is where ggiraph's interactive aesthetics are supplied, including tooltip (text shown on hover), data_id (identifiers used for interactive selection), and onclick (JavaScript run on click).

alpha

Opacity (0 = invisible, 1 = opaque).

color

A color or a formula used for mapping color.

fill

A color for filling, or a formula used for mapping fill.

group

Used for grouping.

linetype

A linetype (numeric or "dashed", "dotted", etc.) or a formula used for mapping linetype.

linewidth

A numerical line width or a formula used for mapping linewidth.

hjust

horizontal and vertical justification of the grob. Each justification value should be a number between 0 and 1. Defaults to 0.5 for both, centering each pixel over its data location.

vjust

horizontal and vertical justification of the grob. Each justification value should be a number between 0 and 1. Defaults to 0.5 for both, centering each pixel over its data location.

interpolate

If TRUE interpolate linearly, if FALSE (the default) don't interpolate.

xlab

Label for x-axis. See also gf_labs().

ylab

Label for y-axis. See also gf_labs().

title

Title, sub-title, and caption for the plot. See also gf_labs().

subtitle

Title, sub-title, and caption for the plot. See also gf_labs().

caption

Title, sub-title, and caption for the plot. See also gf_labs().

stat

A character string naming the stat used to make the layer.

position

Either a character string naming the position function used for the layer or a position object returned from a call to a position function.

show.legend

A logical indicating whether this layer should be included in the legends. NA, the default, includes layer in the legends if any of the attributes of the layer are mapped.

show.help

If TRUE, display some minimal help.

inherit

A logical indicating whether default attributes are inherited.

environment

An environment in which to look for variables not found in data.

Value

A gg object that can be displayed with gf_girafe().

Additional interactive features

  • onclick: JavaScript code (as character string) executed when clicking elements.

  • Additional ggiraph aesthetics may be available depending on the geom.

                     tooltip = ~ paste("MPG:", mpg)) |>
