contingency_table function

Contingency table

Create a contingency table that takes two variables as inputs

contingency_table(
  data = NULL,
  row_var_name = NULL,
  col_var_name = NULL,
  row = NULL,
  col = NULL,
  output_type = "table"
)

Arguments

• data: a data object (a data frame or a data.table)
• row_var_name: name of the variable whose values will fill the rows of the contingency table
• col_var_name: name of the variable whose values will fill the columns of the contingency table
• row: a vector whose values will fill the rows of the contingency table
• col: a vector whose values will fill the columns of the contingency table
• output_type: If output_type == "dt" the output will be a contingency table as a data.table object. If output_type == "table" the output will be a contingency table as a table object. If output_type == "df" the output will be a contingency table as a data.frame object. By default, output_type == "table".

Examples

contingency_table(
data = mtcars,
row_var_name = "am",
col_var_name = "cyl")
contingency_table(row = mtcars$cyl, col = mtcars$am)
contingency_table(mtcars, "am", "cyl", output_type = "dt")
