Interactive Maps with leaflet
leaflet is an interactive mapping package in R. It is excellent for creating web-based maps with interactive features.
Let’s explore a couple of interactive map examples.
R
# Load required packagelibrary(leaflet)# Create an interactive mapleaflet() %>% addTiles() %>% addMarkers( lng = -118.2437, lat = 34.0522, popup = "Los Angeles, CA" ) %>% setView(lng = -118.2437, lat = 34.0522, zoom = 10) |
Output:
Making Static & Interactive Maps With ggvis
- The addMarkers() function adds markers to the map. In this case, a marker is placed at the specified longitude (lng) and latitude (lat) coordinates, representing the location of Los Angeles, CA. The popup argument defines the text that appears when you click on the marker.
- The setView() function specifies the initial view of the map. It sets the center of the map at the specified coordinates (lng and lat) and sets the initial zoom level (zoom).
Making Static & Interactive Maps With ggvis
In R Programming Language data visualization, making static and interactive maps is a common activity. Although the R package ggvis allows for interactive data visualizations, map visualizations are not one of its natural capabilities. For static maps and interactive maps, respectively, we commonly utilize tools like ggplot2 and leaflet.
In this article, we will check how to use ggplot2 and leaflet in R to generate both static and interactive maps.
