  digits = 1,
  show.total = FALSE,
  show.n = FALSE,
  show.missing = FALSE,
  show.stats = TRUE,
  origData = NULL,

)

Arguments

data

A data frame

x

Name of a categorical variable

y

Name of a variable, either continuous or categorical

max.ylev

max.ylev An integer indicating the maximum number of levels of grouping variable ('y'). If a column have unique values less than max.ylev it is treated as a categorical variable. Default value is 5.

digits

Numeric

show.total

logical. Whether or not show total column

show.n

logical. Whether or not show N column

show.missing

logical. Whether or not show missing column

catMethod

An integer indicating methods for categorical variables. Possible values in methods are

0

Perform chisq.test first. If warning present, perform fisher test

1

Perform chisq.test without continuity correction

2

Perform chisq.test with continuity correction

3

perform fisher.test

4

perform prop.trend test
