geom_sf_interactive: interactive sf objects

Description

The geometry is based on ggsf. See the documentation for those functions for more details.

Usage

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

Arguments

mapping

The aesthetic mapping, see geom_point.

data

A data frame, see geom_point.

stat

The statistical transformation to use on the data for this layer, as a string, see geom_point.

position

Postion adjustment, see geom_point.

na.rm
show.legend
inherit.aes
...

other arguments passed on to layer. See geom_point.

Examples

Run this code
# NOT RUN {
# add interactive sf objects to a ggplot -------
library(ggplot2)
library(ggiraph)

## original code: see section examples of ggplot2::geom_sf help file
if (requireNamespace("sf", quietly = TRUE)) {
  nc <- sf::st_read(system.file("shape/nc.shp", package = "sf"), quiet = TRUE)
  gg <- ggplot(nc) +
    geom_sf_interactive(aes(fill = AREA, tooltip = NAME, data_id = NAME))
  ggiraph( ggobj = gg)

  nc_3857 <- sf::st_transform(nc, "+init=epsg:3857")

  # Unfortunately if you plot other types of feature you'll need to use
  # show.legend to tell ggplot2 what type of legend to use
  nc_3857$mid <- sf::st_centroid(nc_3857$geometry)
  gg <- ggplot(nc_3857) +
    geom_sf(colour = "white") +
    geom_sf_interactive(aes(geometry = mid,
        size = AREA, tooltip = NAME, data_id = NAME),
      show.legend = "point")
  girafe( ggobj = gg)
