Normalizes the angle between two directions to the acute angle
in between, i.e. angles between 0 and 90\(^\circ\)
Usage
deviation_norm(x, y = NULL)
Arguments
- x, y
Minuend and subtrahend. Both numeric vectors of angles in degrees.
If y is missing, it treats x as difference. If not, length of subtrahend
y is either 1 or equal to length(x).
Value
numeric vector, acute angles between two directions, i.e. values
between 0 and 90\(^\circ\)
Examples
deviation_norm(175, 5)
#> [1] 10
deviation_norm(c(175, 95, 0), c(5, 85, NA))
#> [1] 10 10 NA
deviation_norm(c(-5, 85, 95, 175, 185, 265, 275, 355, 365))
#> [1] 5 85 85 5 5 85 85 5 5
