Internal tableby functions

A collection of functions that may help users create custom functions that are formatted correctly.

as.tbstat(
  x,
  oldClass = NULL,
  sep = NULL,
  parens = NULL,
  sep2 = NULL,
  pct = NULL,
  ...
)

as.countpct(
  x,
  ...,
  which.count = setdiff(seq_along(x), which.pct),
  which.pct = 0L
)

as.tbstat_multirow(x)

Arguments

x	Usually a vector.
oldClass	class(es) to add to the resulting object.
sep	The separator between x[1] and the rest of the vector.
parens	A length-2 vector denoting parentheses to use around x[2] and x[3].
sep2	The separator between x[2] and x[3].
pct	For statistics of length 2, the symbol to use after the second one. (It's called "pct" because usually the first statistic is never a percent, but the second often is.)
...	arguments to pass to as.tbstat.
which.count	Which statistics are counts? The default is everything except the things that are percents.
which.pct	Which statistics are percents? The default is 0, indicating that none are.

Details

The vignette has an example on how to use these.

as.tbstat defines a tableby statistic with its appropriate formatting.

as.countpct adds another class to as.tbstat to use different "digits" arguments (i.e., digits.count or digits.pct). See tableby.control.

as.tbstat_multirow marks an object (usually a list) for multiple-row printing.
