Symmetry Index — pr_calc_symmetry_index • pressR

Computes the symmetry index (SI%) between left and right sides of a layout for a given parameter. SI = (L - R) / (0.5 * (L + R)) * 100.

Usage

pr_calc_symmetry_index(
  trial,
  parameter = c("peak_pressure", "mean_pressure", "force", "contact_area")
)

Arguments

trial: A pr_trial object.
parameter: Character. One of "peak_pressure", "mean_pressure", "force", "contact_area". Default "peak_pressure".

Value

Numeric scalar. Positive values indicate left dominance.

Examples

pr_calc_symmetry_index(pr_example_trial("saddle_horse"))
