fc_locations_link: Link event locations

In shawnsanto/scoutr: Soccer Data Manipulation and Visualization

Description

This function converts data from a tibble to a simple feature object by adding a linestring geometry that links the starting and ending locations of each event in data.

Usage

fc_locations_link(data, start_loc, end_loc)

Arguments

data	A data frame with event location data.
start_loc	A character vector identifying the x and y coordinates for the start of an event in data.
end_loc	A character vector identifying the x and y coordinates for the end of an event in data.

Value

A simple feature object with a new variable named geometry. The variable geometry is a linestring object.
