SpatialLinesDataFrame-class function

a class for spatial lines with attributes

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

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.
