Include Tables, Images and Graphs in Leaflet Popups

leafpop creates HTML strings to embed tables, images or graphs in popups of interactive maps created with packages 'leaflet' or 'mapview'. Handles local paths to images on the file system or remote urls. Handles graphs created with 'base' graphics, 'lattice' or 'ggplot2' as well as interactive plots created with 'htmlwidgets'.

Installation

You can install the released version of leafpop from CRAN with:

install.packages("leafpop")

Or the development version from GitHub:

# install.packages("devtools")
devtools::install_github("r-spatial/leafpop")

Examples

popupTable

library(leaflet)

leaflet() %>%
  addTiles() %>%
  addCircleMarkers(data = breweries91,
                   popup = popupTable(breweries91))

addPopupImages & popupImage

library(sf)
library(leaflet)

pnt = st_as_sf(data.frame(x = 174.764474, y = -36.877245),
                coords = c("x", "y"),
                crs = 4326)

img = "http://bit.ly/1TVwRiR"

leaflet() %>%
  addTiles() %>%
  addCircleMarkers(data = pnt, group = "pnt") %>%
  addPopupImages(img, group = "pnt")

Alternatively you can bind the images directly in in the add* call, however, this will not include the images when the map is saved using mapshot or saveWidget. This options is basically available for backward compatibility only.

leaflet() %>%
  addTiles() %>%
  addCircleMarkers(data = pnt, popup = popupImage(img, src = "remote"))

popupGraph

library(sf)
library(leaflet)
library(lattice)

pnt = st_as_sf(data.frame(x = 174.764474, y = -36.877245),
                coords = c("x", "y"),
                crs = 4326)

p2 = levelplot(t(volcano), col.regions = terrain.colors(100))

leaflet() %>%
  addTiles() %>%
  addCircleMarkers(data = pnt, group = "pnt") %>%
  addPopupGraphs(list(p2), group = "pnt", width = 300, height = 400)

Alternatively you can bind the graphs directly in in the add* call, however, this will not include the graphs when the map is saved using mapshot or saveWidget. This options is basically available for backward compatibility only.

leaflet() %>%
  addTiles() %>%
  addCircleMarkers(data = pnt, popup = popupGraph(p2, width = 300, height = 400))
