R_crit: Mean resultant length critical value

In maxgav13/GMisc: Miscellaneous Functions for Geology (and its areas)

Mean resultant length critical value

Description

Calculates the critical value for the mean resultant length for directional statistics.

Usage

R_crit(n, case = "2D", conf.level = 0.95)

Arguments

n	Sample size of the correlated values
case	String idicating for which case to calculate the critical value, 2D or 3D
conf.level	Confidence level to use for the critical value (Default is 0.95, and see details section below)

Details

The result of this function is mostly to be used with dir_unif_test_xD(), but can be used as standalone. The options for confidence level are 0.99, 0.975, 0.95, or 0.90

Value

Mean resultant length's critical value for a given sample size
