tally: Tabulate categorical data

Description

Tabulate categorical data

Usage

tally(x, ...)
## S3 method for class 'tbl':
tally(x, wt, sort = FALSE, ..., envir = parent.frame())
## S3 method for class 'default':
tally(x, data = parent.frame(), format = c("count",
  "proportion", "percent", "data.frame", "sparse", "default"),
  margins = FALSE, quiet = TRUE, subset, useNA = "ifany", ...)

Arguments

x

an object

...

additional arguments passed to table

wt

for weighted tallying, see tally in dplyr

sort

a logical, see tally in dplyr

envir

an environment in which to evaluate

data

a data frame or environment in which evaluation occurs. Note that the default is data=parent.frame(). This makes it convenient to use this function interactively by treating the working envionment as if it were a data frame. But this may no

format

a character string describing the desired format of the results. One of 'default', 'count', 'proportion', 'percent', 'data.frame', 'sparse', or 'default'

margins

a logical indicating whether marginal distributions should be displayed.

quiet

a logical indicating whether messages about order in which marginal distributions are calculated should be surpressed. See addmargins.

subset

an expression evaluating to a logical vector used to select a subset of data

useNA

as in table, but the default here is "ifany".

Details

The dplyr package also exports a tally function. If x inherits from class "tbl", then dplyr's tally is called. This makes it easier to have the two package coexist.

Examples

if (require(mosaicData)) {
tally( ~ substance, data=HELPrct)
tally( ~ substance & sex , data=HELPrct)
tally( sex ~ substance, data=HELPrct)   # equivalent to tally( ~ sex | substance, ... )
tally( ~ substance | sex , data=HELPrct)
tally( ~ substance | sex , data=HELPrct, format='count')
tally( ~ substance & sex , data=HELPrct, format='percent')
# force NAs to show up
tally( ~ sex, data=HELPrct, useNA="always")
# show NAs if any are there
tally( ~ link, data=HELPrct)
# ignfore the NAs
tally( ~ link, data=HELPrct, useNA="no")
}
