Compute Various Asymmetry Metrics Between Two Sides

Source: R/subtyper.R

This function computes different types of asymmetry metrics given left and right side measurements. It can return standard asymmetry indices, including the absolute difference, symmetry-adjusted mean, proportional asymmetry, and more.

asymmetry(left, right, name_of_measurement)

Arguments

left

Numeric. The value representing the left side of the measurement.

right

Numeric. The value representing the right side of the measurement.

name_of_measurement

Character. The name of the asymmetry measure to compute. Options include:

  • "absolute_difference": Absolute difference between left and right.

  • "proportional_asymmetry": Proportional asymmetry.

  • "symmetry_adjusted_mean": Symmetry-adjusted mean (SAM).

  • "relative_asymmetry": (Left - Right) / (Left + Right).

  • "asymmetry_index": (|Left - Right|) / ((Left + Right) / 2).

Value

Numeric value of the computed asymmetry measure.

Examples

asymmetry(5, 3, "absolute_difference")
#> [1] 2
asymmetry(10, 8, "symmetry_adjusted_mean")
#> [1] 7
