Simple table of counts and percentages

1	Tab(var, digits = 2, useNA = c("no", "ifany", "always"))

`var`	A variable.
`digits`	An integer indicating the number of decimals places to be used for rounding.
`useNA`	Should `NA` values be tabulated? Defaults to `"no"`.

If useNA = "ifany" then NA values will be included if any exist. If useNA = "always" then if var does not contain any NA values a count, percentage, and cumulative percentage of 0 will be reported.

A table of counts, percentages, and cumulative percentages for levels of var.
