n_perc: Count and Percentage

Description

A function for calculating and formatting counts and percentages.

Usage

n_perc(x, digits = getOption("qwraps2_frmt_digits", 2), na_rm = FALSE,
  show_denom = "ifNA", show_symbol = TRUE,
  markup = getOption("qwraps2_markup", "latex"))
perc_n(x, digits = getOption("qwraps2_frmt_digits", 2), na_rm = FALSE,
  show_denom = "ifNA", markup = getOption("qwraps2_markup", "latex"))
n_perc0(x, digits = 0, na_rm = FALSE, show_denom = "never",
  show_symbol = FALSE, markup = getOption("qwraps2_markup", "latex"))

Arguments

x

a 0:1 or boolean vector

digits

digits to the right of the decimal point to return in the percentage estimate.

na_rm

if true, omit NA values

show_denom

defaults to "ifNA". Other options are "always" or "never".

show_symbol

if TRUE (default) the percent symbol is shown, else it is supressed.

markup

latex or markdown

Value

• a character vector of the formatted values

Details

Default behavior will return the count of successes and the percentage as "N (ppcan be controlled by setting na.rm = TRUE. In this case, the number of non-missing values will be reported by default. Omission of the non-missing values can be controlled by setting show_denom = "never".

The function n_perc0 uses a set of default arguments which may be advantageous for use in building tables.

Examples

n_perc(c(0, 1,1, 1, 0, 0), show_denom = "always")
n_perc(c(0, 1,1, 1, 0, 0, NA), na_rm = TRUE)

n_perc(mtcars$cyl == 6)

set.seed(42)
x <- rbinom(4269, 1, 0.314)
n_perc(x)
n_perc(x, show_denom = "always")
n_perc(x, show_symbol = FALSE)

# n_perc0 examples
n_perc0(c(0, 1,1, 1, 0, 0))
n_perc0(mtcars$cyl == 6)
