SpatialLinesDataFrame-class: a class for spatial lines with attributes

Description Objects from the Class Slots Extends Methods Note Author(s) See Also

Description

this class holds data consisting of (sets of lines), where each set of lines relates to an attribute row in a data.frame

Objects from the Class

can be created by the function SpatialLinesDataFrame

Slots

data:

Object of class data.frame containing the attribute table

lines:

Object of class "list"; see SpatialLines-class

bbox:

Object of class "matrix"; see Spatial-class

proj4string:

Object of class "CRS"; see CRS-class

Extends

Class "SpatialLines", directly. Class "Spatial", by class "SpatialLines".

Methods

Methods defined with class "SpatialLinesDataFrame" in the signature:

[

signature(x = "SpatialLinesDataFrame"): subset rows or columns; in case of row subsetting, the line sets are also subsetted; NAs are not permitted in the row index

coordinates

signature(obj = "SpatialLinesDataFrame"): retrieves a list with lists of coordinate matrices

show

signature(object = "SpatialLinesDataFrame"): print method

plot

signature(x = "SpatialLinesDataFrame"): plot points

lines

signature(object = "SpatialLinesDataFrame"): add lines to plot

rbind

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

Note

rbind for SpatialLinesDataFrame is only possible for objects with unique IDs. If you want to rbind objects with duplicated IDs, seespChFIDs.
