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

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
.
