Class "SpatialMultiPoints"

Class for (irregularly spaced) MultiPoints

Keywords
classes
Objects from the Class

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

Slots

coords:

Object of class "list", containing the coordinates of point sets (each list element is a matrix)

bbox:

Object of class "matrix", with bounding box

proj4string:

Object of class "CRS", projection string

Extends

Class "Spatial", directly.

Methods

[

signature(x = "SpatialMultiPoints"): subsets point sets

coerce

signature(from = "SpatialPoints", to = "data.frame"): coerce to data.frame

coordinates

signature(obj = "SpatialMultiPoints"): retrieves all the coordinates, as one single matrix

plot

signature(x = "SpatialPoints", y = "missing"): plot points

summary

signature(object = "SpatialPoints"): summarize object

points

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

show

signature(object = "SpatialPoints"): prints coordinates

rbind

signature(object = "SpatialPoints"): rbind-like method

plot method arguments

The plot method for “SpatialPoints” objects takes the following arguments:

x

object of class SpatialPoints

pch

default 3; either an integer specifying a symbol or a single character to be used as the default in plotting points

axes

default FALSE; a logical value indicating whether both axes should be drawn

add

default FALSE; add to existing plot

xlim

default NULL; the x limits (x1, x2) of the plot

ylim

default NULL; the y limits of the plot

...

passed through

setParUsrBB

default FALSE; set the par “usr” bounding box, see note in Spatial-class

cex

default 1; numerical value giving the amount by which plotting text and symbols should be magnified relative to the default

col

default 1; default plotting color

lwd

default 1; line width

bg

default 1; colour to be used for the background of the device region
