In qwraps2: Quick Wraps 2

Mean and Standard deviation

Description

A function for calculating and formatting means and standard deviations.

Usage

mean_sd(
  x,
  digits = getOption("qwraps2_frmt_digits", 2),
  na_rm = FALSE,
  show_n = "ifNA",
  denote_sd = "pm",
  markup = getOption("qwraps2_markup", "latex"),
  ...
)

Arguments

x	a numeric vector
digits	digits to the right of the decimal point to return in the percentage estimate.
na_rm	if true, omit NA values
show_n	defaults to "ifNA". Other options are "always" or "never".
denote_sd	a character string set to either "pm" or "paren" for reporting 'mean \pm sd' or 'mean (sd)'
markup	character string with value "latex" or "markdown"
...	pass through

Details

Given a numeric vector, mean_sd will return a character string with the mean and standard deviation. Formatting of the output will be extended in future versions.

Value

a character vector of the formatted values
