df_to_table: Convert a data frame to a contingency table

In rfriend: Provides Batch Functions and Visualisation for Basic Statistical Procedures

Convert a data frame to a contingency table

Description

Convert a data frame to a contingency table

Usage

df_to_table(df, label_col = NULL)

Arguments

df	A data frame. Either (a) one column contains row labels and the rest are numeric, (b) a fully numeric data frame with meaningful rownames() set, or (c) a fully numeric data frame with no row labels at all (in which case the data frame is coerced directly to a table without row labels).
label_col	Index or name of the column containing row labels. If NULL (default), the function auto-detects the first character/factor column. If no such column is found, the function falls back to using rownames(df) when these are meaningful, otherwise it coerces the data frame to a table as-is.

Value

A contingency table.
