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",
  show_symbol = FALSE,
  markup = getOption("qwraps2_markup", "latex"),
  ...
)
n_perc0(
  x,
  digits = 0,
  na_rm = FALSE,
  show_denom = "never",
  show_symbol = FALSE,
  markup = getOption("qwraps2_markup", "latex"),
  ...
)

Value

a character vector of the formatted values

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 suppressed.

markup

latex or markdown

...

pass through

Details

Default behavior will return the count of successes and the percentage as "N (pp can 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)
