R Documentation

Cross Tabulation and Table Creation

Description

Upgrades table to a generic function and implements a method for ff vectors which works for ff factors. For other arguments passed on to table, uses table

Usage

table(..., exclude = if (useNA == "no") c(NA, NaN), 
useNA = c("no", "ifany", "always"), dnn = list.names(...), deparse.level = 1)

table(..., exclude = if (useNA == "no") c(NA, NaN), 
useNA = c("no", "ifany", "always"), dnn = list.names(...), deparse.level = 1)

Arguments

`...`	`ff` factors or `ff` integers
`exclude`	see `table`
`useNA`	see `table`
`dnn`	see `table`
`deparse.level`	see `table`

Details

table.ff uses the cross-classifying factors to build a contingency table of the counts at each combination of factor levels.
If ... does not contain factors, unique.ff will add a levels attribute to the non-factors.
