Description

Return the percentages of a cross-tabulation table (2 dimensions or more) with formatting and printing options.

Usage

prop(tab, ...)
prop_table(
  tab,
  digits = 1,
  total = TRUE,
  percent = FALSE,
  drop = TRUE,
  n = FALSE,
  ...
)
# S3 method for data.frame
prop(
  tab,
  digits = 1,
  total = TRUE,
  percent = FALSE,
  drop = TRUE,
  n = FALSE,
  ...
)
# S3 method for matrix
prop(
  tab,
  digits = 1,
  total = TRUE,
  percent = FALSE,
  drop = TRUE,
  n = FALSE,
  ...
)
# S3 method for tabyl
prop(tab, digits = 1, total = TRUE, percent = FALSE, n = FALSE, ...)

Value

The result is an object of class table and proptab.

Arguments

tab: frequency table
...: parameters passed to other methods
digits: number of digits to display
total: if TRUE, add a column with the sum of percentages and a row with global percentages
percent: if TRUE, add a percent sign after the values when printing
drop: if TRUE, lines or columns with a sum of zero, which would generate NaN percentages, are dropped. Unused for tables of 3 dimensions or more (always `FALSE`).
n: if TRUE, display number of observations per row and per column.

Examples

Run this code

## Sample table
data(Titanic)
tab <- apply(Titanic, c(1,4), sum)
## Percentages
prop(tab)
## Percentages with custom display
prop(tab, digits=2, percent=TRUE, total=FALSE, n=TRUE)
## Could be applied to a table of 3 dimensions or more
