Find coordinates that need flipping

The orientation of coordinates (e.g. is a serve going from the lower part of the court to the upper, or vice-versa?) depends on how the scout entered them. This function finds coordinates that require flipping, so that all attacks/serves/whatever can be plotted with the same orientation

Usage

dv_find_to_flip_coordinates(x, target_start_end = "lower")

Arguments

x

datavolleyplays: the plays component of a datavolley object as returned by dv_read

target_start_end

string: "lower" or "upper"

Value

A logical index with length equal to the number of rows of x. TRUE indicates rows of x that need their coordinates flipped
