A set of descriptive statistics for circular data
Usage
circ_descr(x, w = NULL, d = NULL, na.rm = FALSE)
Arguments
- x
vector of angles
- w
weights for the values in the vector
- d
correction for the bias for data with known spacing
- na.rm
a logical value indicating whether NA values should be removed before the computation proceeds
Value
a list with descriptive statistics
mu - mean
sigma - standard deviation
skew_pewsey - skewness as defined by Pewsey
skew_fischer - skewness as defined by Fischer
rho - mean resultant length
skew_rel_to_zero - skewness relative to zero
Examples
x <- c(rnorm(50, 0, 0.5), rnorm(20, 1, 0.5))
