R: a class for spatial lines with attributes

SpatialLinesDataFrame-class {sp} | R Documentation

## a class for spatial lines with attributes

### 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, see`spChFIDs`.
