  data,
  col_var,
  ...,
  add_total = FALSE,
  percentages = FALSE,
  chi_square = FALSE
)

Arguments

data

a tibble or a tdcmm model

col_var

Independent (column) variable.

...

Dependent (row) variables.

add_total

Logical indicating whether a 'Total' column should be computed. Defaults to FALSE.

percentages

Logical indicating whether to output column-wise percentages instead of absolute values. Defaults to FALSE.

chi_square

Logical indicating whether a Chi-square test should be computed. Test results will be reported via message(). Defaults to FALSE.

Value

a tdcmm model
