prop: Compute proportions, percents, or counts for a single level

Description

Compute proportions, percents, or counts for a single level

Usage

prop(x, data = parent.frame(), useNA = "no", ..., level = NULL,
  long.names = TRUE, sep = ".", format = c("proportion", "percent",
  "count"), quiet = TRUE, pval.adjust = FALSE)
prop1(..., pval.adjust = TRUE)
count(x, data = parent.frame(), ..., format = "count")
perc(x, data = parent.frame(), ..., format = "percent")

Arguments

x

an R object, usually a formula

data

a data frame in which x is to be evaluated

useNA

an indication of how NA's should be handled. By default, they are ignored.

level

the level for which counts, proportions or percents are calculated

long.names

a logical indicating whether long names should be when there is a conditioning variable

sep

a character used to separate portions of long names

format

one of proportion, percent, or count, possibly abbrevaited

quiet

a logical indicating whether messages regarding the target level should be supressed.

pval.adjust

a logical indicating whether the "p-value" adjustment should be applied. This adjustment adds 1 to the numerator and denominator counts.

…

arguments passed through to tally

Details

prop1 is intended for the computation of p-values from randomization distributions and differs from prop only in its default value of pval.adjust.

Examples

if (require(mosaicData)) {
prop( ~sex, data=HELPrct)
prop( ~sex, data=HELPrct, level='male')
count( ~sex | substance, data=HELPrct)
prop( ~sex | substance, data=HELPrct)
perc( ~sex | substance, data=HELPrct)
}
