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

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.
