A package providing classes and methods for spatial data: points, lines, polygons and grids
Class "CRS" of coordinate reference system arguments
Class "DMS" for degree, minute, decimal second values
create objects of class SpatialLines or SpatialLinesDataFrame
a class for spatial lines with attributes
create objects of class SpatialMultiPoints or SpatialMultiPointsDataFrame
create objects of class SpatialPoints or SpatialPointsDataFrame
create objects of class SpatialPolygons or SpatialPolygonsDataFrame
constructs SpatialXxxDataFrame from geometry and attributes
Make SpatialPolygons object from GridTopology object
read/write to/from (ESRI) asciigrid format
blue-pink-yellow color scheme, which also prints well on black/white printers
Convert character vector to DMS-class object
set spatial coordinates to create a Spatial object, or retrieve spatial coordinates from a Spatial object
retrieve or assign coordinate names for classes in sp
retrieve spatial dimensions from spatial data
disaggregate SpatialLines, SpatialLinesDataFrame, SpatialPolygons, or SpatialPolygonsDataFrame objects
Methods for Function elide in Package 'maptools'
rearrange data in SpatialPointsDataFrame or SpatialGridDataFrame for plotting with spplot (levelplot/xyplot wrapper)
Methods for retrieving the geometry from a composite (geometry + attributes) object
specify spatial data as being gridded, or find out whether they are
create neighbourhood (nb) object from grid geometry
Create N-S and E-W grid lines over a geographic region
Image or contour method for gridded spatial data; convert to and from image data structure
Sets or retrieves projection attributes on classes extending SpatialData
deprecated function to load the Meuse data set
Calculate aspect ratio for plotting geographic maps; create nice degree axis labels
Merge a Spatial* object having attributes with a data.frame
Prediction Grid for Meuse Data Set, geographical coordinates
consistent spatial overlay for points, grids and polygons
panel and panel utility functions for spplot
Retrieve polygons from SpatialPolygonsDataFrame object
sets spatial coordinates to create spatial data, or retrieves spatial coordinates
Methods for Function recenter in Package 'sp'
Euclidean or Great Circle distance between points
spTransform for map projection and datum transformation
Plot methods for spatial data with attributes
sample point locations in (or on) a spatial object
Compute surface area of a digital elevation model.
find point pairs with equal spatial coordinates
