Usage

prop(tab, ...)

prop_table(
  tab,
  digits = 1,
  total = TRUE,
  percent = FALSE,
  drop = TRUE,
  n = FALSE,
  ...
)

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

## S3 method for class 'matrix'
prop(
  tab,
  digits = 1,
  total = TRUE,
  percent = FALSE,
  drop = TRUE,
  n = FALSE,
  ...
)

## S3 method for class 'tabyl'
prop(tab, digits = 1, total = TRUE, percent = FALSE, n = FALSE, ...)

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.

Value

The result is an object of class table and proptab.

Examples

## Sample table
data(Titanic)
tab <- apply(Titanic, c(1,4), sum)
## Percentages

## Percentages with custom display

## Could be applied to a table of 3 dimensions or more
