Weighted circular parameters

Usage

weighted_circ_mean(x, w, period = NULL, na.rm = FALSE)

weighted_circ_mean2(x, w, na.rm = FALSE)

weighted_circ_sd(x, w, na.rm = FALSE)

weighted_circ_rho(x, w, na.rm = FALSE)

Arguments

x

vector of values (in radians, unless period is set)

w

vector of weights

period

if not NULL, the period of the circular space (e.g., 180 or 360); x is then converted to radians as x / period * 2 * pi and the result is converted back to the same period

na.rm

a logical value indicating whether NA values should be removed before the computation proceeds

Value

weighted mean of values in the vector

Functions

  • weighted_circ_mean(): weighted circular mean

  • weighted_circ_mean2(): an alternative way to compute weighted circular mean (the results are the same)

  • weighted_circ_sd(): weighted circular SD

  • weighted_circ_rho(): weighted mean resultant length

Examples

x <- rnorm(1000, 0, 0.5)
w <- runif(1000, 0, 1)
weighted.mean(x, w)
#> [1] -0.0007545474
weighted_circ_mean(x, w)
#> [1] 6.034346e-05
