Like for other plots, there are different approaches in R to make maps. You can use “base plot” in many cases. Alternatively use levelplot, either via the spplot function (implemented in sp and raster) or via the rasterVis package. Here are some brief examples about making maps.

Static maps are the most common type of visual output from geocomputation. Standard formats include .png and .pdf for raster and vector outputs respectively. Initially, static maps were the only type of maps that R could produce.
25 paź 2018 · In this part, we will cover the fundamentals of mapping using ggplot2 associated to sf, and presents the basics elements and parameters we can play with to prepare a map. Maps are used in a variety of fields to express data in an appealing and interpretive way.
The raster package provides classes and functions to manipulate geographic (spatial) data in ’raster’ format. Raster data divides space into cells (rectangles; pixels) of equal size (in units of the coor-
A RasterLayer can easily be created from scratch using the function raster. The default settings will create a global raster data structure with a longitude/latitude coordinate reference system and 1 by 1 degree cells. You can change these settings by providing additional arguments such as xmn, nrow, ncol, and/or crs, to the function.
The raster package¶ This vignette describes the R package raster. A raster is a spatial (geographic) data structure that divides a region into rectangles called “cells” (or “pixels”) that can store one or more values for each of these cells.
We create maps of areal data using several functions and parameters of the mapping packages. We also briefly describe how to plot point and raster data. Then, we show how to create maps of flows between locations with the flowmapblue package (Boyandin 2023).
