string_line: Plot a recreation of E.J. Marey's graphical train schedule...

In jsphdms/stringliner:

Description

Stations are plotted vertically according to their relative distance. This means the slope of each line corresponds to the speed of the train.

Usage

string_line(route = "glq_edb_via_fkk")

Arguments

route

String. The name of a csv file (without extension) in the extdata directory

Details

This plot requires two data tables: a timetable and the distances between stations. This can potentially lead to redundancy (repetition of stations) so the demonstration datasets store these two tables in a special format as csv files. The timetable is organised with a row for each journey and a column for each station. Relative distances are stored in the headers. This function parses this dataset and then plots a stringline chart.

Value

A plot object. A stringline chart.

Examples

string_line()
string_line("london_edinburgh_test")
