Reading, writing, manipulating, analyzing and modeling of spatial data. The package implements basic and high-level functions for raster data and for vector data operations such as intersections. This package has been superseded by the "terra" package <https://CRAN.R-project.org/package=terra>.

Fast alternatives to several relatively slow 'raster' package
functions. For large rasters, the functions run from 5 to
approximately 100 times faster than the 'raster' package functions
they replace. The 'fasterize' package, on which one function in this
package depends, includes an implementation of the scan line
algorithm attributed to Wylie et al. (1967)
<doi:10.1145/1465611.1465619>.

This is a wrapper function for image(), which makes reasonable
raster plots with nice axis and other useful features.

Kernel Based Estimates on in-Memory Raster Images
Performs kernel based estimates on in-memory raster images
from the raster package.  These kernel estimates include local means
variances, modes, and quantiles.  All results are in the form of
raster images, preserving original resolution and projection attributes.

A Raster Where Cells are Generic Objects
c(person(given="Emanuele",family="Cordano",role = c("aut","cre"),email = "emanuele.cordano@gmail.com"))
A S4 class has been created such that complex operations can be
executed on each cells of a raster map. The raster of objects contains the
traditional raster map with the addition of a list of generic objects: one
object for each raster cells. It allows to write few lines of R code for complex
map algebra. Two environmental applications about frequency analysis of raster
map of precipitation and creation of a raster map of soil water retention curves
have been presented.

Visualization methods for the raster package.
Oscar Perpiñán Lamigueiro and Robert Hijmans
The raster package defines classes and methods for spatial
raster data access and manipulation. The rasterVis package
complements raster providing a set of methods for enhanced
visualization and interaction.
