Creating interactive maps in R allows users to explore geographical data dynamically. The power of R's mapping capabilities is enhanced by libraries such as leaflet, which enables the integration of various map layers and interactive elements like popups, markers, and overlays. This functionality can be applied to both simple and complex datasets, offering a visual tool for analysis and presentation.

To start building interactive maps, R provides a range of functions and packages. Below is an outline of some essential steps:

  • Install necessary libraries like leaflet and sf.
  • Prepare and clean your geographical data.
  • Create a base map using predefined map tiles or custom layers.
  • Add interactive elements such as markers or heatmaps.

Tip: Ensure your dataset is in the correct spatial format (e.g., shapefiles or geoJSON) for better compatibility with mapping functions.

The following table summarizes some popular libraries for interactive mapping in R:

Library Purpose Key Features
leaflet Interactive maps Marker clusters, popups, heatmaps
mapview Quick visualization Automatic zoom levels, interactive layers
tmap Static and interactive maps Thematic maps, flexible layouts
