sd_rs function

Calculate standard deviation for each location under each regime.

sd_rs(x, label)

Arguments

• x: A data.frame or matrix.
• label: A vector of regime labels. Its length must be the same as the number rows in x.

Returns

A list of standard deviations for each regime.

Examples

set.seed(123)
x <- matrix(rnorm(200), nrow = 100)
label <- sample(1:2, 100, replace = TRUE)
sd_rs(x, label = factor(label))
