Standard Deviation

Description

Compute the sample standard deviation

Usage

sdev(x, rounding = 2, na.rm = FALSE, details = FALSE, grouped = TRUE)

Arguments

`x`	R object (list) of class leem. Use `new_leem()` function.
`rounding`	Numerical object. Rounds the values in its first argument to the specified number of decimal places (default `2`).
`na.rm`	a logical value indicating whether `NA` values should be stripped before the computation proceeds.
`details`	Logical object. Details of data (default `FALSE`).
`grouped`	Logical object. Determines whether the measure of position result will be based on grouped data or not (default `TRUE`).

Examples

# Example 1: Poisson data
rpois(30, 2.5) |>
  new_leem() |>
  sdev()
# Example 2: Normal data
rnorm(50, 100, 2.5) |>
  new_leem(variable = 2) |>
  sdev(grouped = FALSE)
