Class "SpatialPoints" ~~~

Description

Class for (irregularly spaced) points

Objects from the Class

Objects can be created by calls of the form SpatialPoints(x).

Slots

coords:

Object of class "matrix", containing the coordinates (each row is a point)

bbox:

Object of class "matrix", with bounding box

proj4string:

Object of class "CRS", projection string

Extends

Class "Spatial", directly.

Methods

[

signature(x = "SpatialPoints"): subsets the points; only rows can be subsetted

coerce

signature(from = "SpatialPoints", to = "data.frame"): retrieves the data part

coerce

signature(from = "data.frame", to = "SpatialPoints"): sets coordinates, which may be in a data frame

coerce

signature(from = "matrix", to = "SpatialPoints"): set coordinates, which may be in a matrix

coordinates

signature(obj = "SpatialPoints"): retrieves the coordinates, as matrix

plot

signature(x = "SpatialPoints"): plot point symbols

points

signature(x = "SpatialPoints"): add point symbols to plot

show

signature(object = "SpatialPoints"): prints coordinates

Examples

x = c(1,2,3,4,5)
y = c(3,2,5,1,4)
S <- SpatialPoints(cbind(x,y))
S <- SpatialPoints(list(x,y))
S <- SpatialPoints(data.frame(x,y))
S
plot(S)
