## S4 method for signature 'kRp.corpus'
lex.div(
  txt,
  summary = TRUE,
  mc.cores = getOption("mc.cores", 1L),
  char = "",
  quiet = TRUE,
  ...
)

`txt`	An object of class `kRp.corpus`.
`summary`	Logical, determines if the `summary` slot should automatically be updated by calling `summary` on the result.
`mc.cores`	The number of cores to use for parallelization, see `mclapply`.
`char`	Character vector to specify measures of which characteristics should be computed, see `lex.div` for details.
`quiet`	Logical, if `FALSE` shows a status bar for some measures of each text, see `lex.div` for details.
