The leaflet is an open-source JavaScript library for interactive web maps. The leaflet is designed with simplicity, performance, and usability in mind. It’s lightweight, simple, and flexible, and is probably the most popular open-source mapping library at the moment.
The leaflet has many features that we can easily use on our project or research as follow
Before we begin to build the visualization, make sure we fulfil the following requirements:
leaflet
, leaflet.extras
, and dplyr
We run these lines of code in the console of R Studio to install the required packages.
install.packages("tidyverse") install.packages("leaflet")
Next we read in our data with the read_csv() function from the tidyverse. You may need to alter the file path of your csv in the read_csv() function.
library("tidyverse")
library("leaflet")
You create a Leaflet map with these basic steps:
leaflet()
.addTiles
, addMarkers
, addPolygons
) to modify the map widget.Here’s a basic example:
library(leaflet)
m <- leaflet() %>%
# Add default OpenStreetMap map tiles
addTiles() %>%
addMarkers(lng=77.231299, lat=28.613869, popup="Hello World")
# Print the map
m
Use markers to call out points on the map. Marker locations are expressed in latitude/longitude coordinates, and can either appear as icons or as circles.
Circle markers are much like regular circles, except that their radius in onscreen pixels stays constant regardless of zoom level.
You can use their default appearance:
library(leaflet)
m <- leaflet() %>%
# Add default OpenStreetMap map tiles
addTiles() %>%
addCircleMarkers(lng=77.231299, lat=28.613869, popup="Hello World")
# Print the map
m
Hence, we saw what is leaflet, how to install and load leaflet in R, how to use leaflet, and also how to make plots in the leaflet.
