tidytlg (version 0.11.0)

statlist: Create a statlist interface for a table

Description

The statlist is the interface for the presentation of data in a tidytlg table.

Usage

statlist(stats, ...)

Value

A statlist object that can be passed in the statlist argument of freq, nested_freq, or univar.

Arguments

stats

(required) A character vector of statistics to display in the table.

...

(optional) Additional configuration for stats. See sections below for allowable arguments.

<code>Statlists</code> for <code>freq()</code> and <code>nested_freq()</code>

freq() statlists can be composed of n (count), N (denominator), and x.x (percentage, formatted with or without a percent sign). Denominators will include missing values if the 'display_missing' argument is TRUE, otherwise they will be excluded. They can be arranged in the following ways:

• n

• n/N

• n (x.x)

• n (x.x%)

• n/N (x.x)

• n/N (x.x%)

The following other configurations are supported:

• denoms_by - Controls what groupings of variables should define the denominator. Variables should be passed as a quoted vector

• distinct - A boolean value. Should the numerator reflect distinct USUBJIDs or event counts. Defaults to TRUE which captures distinct subjects.

• distinct_by - A character value used to select the variable that should be used to "distinct" the frequency tables. Defaults to USUBJID.

• zero_denom - The string to display when there are no records found in an entire denominator group. Defaults to -

• zero_n - The string to display when there are no records found for a numerator. Defaults to 0.

where GeoMEAN: Geometric Mean, CV: Coefficient of Variation, GSD: Geometric standard deviation, GSE: Geometric standard error, MEAN_CI: Mean (95% C.I.), GeoMEAN_CI: Geometric Mean (95% C.I.). In calculating geometric statistics, if there are zero values in the inputs, zero values will be excluded before calculating geometric statistics.

Examples

freq(
  mtcars,
  colvar = "gear",
  rowvar = "cyl",
  rowbyvar = "am",
  statlist = statlist("n/N (x.x)",
    distinct = FALSE,
    denoms_by = c("gear", "am"),
    zero_denom = "_0_"
  )
