TimeOrderedRecords-class {trip}

A class for the identifiers of DateTime and ID records in spatial data.

Description

The main use of this class and creator function is for SpatialPointsDataFrame-classs which are used with TimeOrderedRecords for the class trip.

Value

S4 object, TimeOrderedRecords (a class to hold the names of the date-time and id columns)

Slots

TOR.columns:

2-element vector of class "character"

Note

Future versions may change significantly, this class is very basic and could probably be implemented in a better way. Specifying TOR columns by formula would be a useful addition.
