Arguments

...

objects which can be interpreted as factors (including character strings), or a list (or data frame) whose components can be so interpreted

exclude

Examples

## Simple frequency distribution
table(rpois(100,5))

attach(warpbreaks)
## Check the design:

table(state.division, state.region)

data(airquality)
