compute_o_diff: Compute orientation difference

In guga31bb/ngscleanR: Helper Functions for Cleaning Player Tracking Data

Description

Compute difference in orientation between direction player is currently facing and orientation if player were facing towards a given x and y location.

Usage

compute_o_diff(df, prefix = "qb")

Arguments

df	A dataframe containing x, y, o, "prefix"_x, and "prefix"_y
prefix	(default = "qb"). Columns prefix_x and prefix_y must be contained in df. These columns contain the x and y locations that will be used to calculate orientation difference.

Value

Original dataframe with o_to_"prefix" added, which is the difference in orientation in degrees between the way the player is facing and where the "prefix" player is (0 is facing directly at the "prefix" player, 180 is directly away).

Examples

df <- tibble::tibble("x" = 20, "y" = 30, "o" = 270, "qb_x" = 10, "qb_y" = 25)
df <- compute_o_diff(df)
str(df)
