given a data frame with two ways to group rows, summarize and give examples of situations where the mapping is not 1-1

summarize_map(data, x_cols, y_cols, n_examples = 4, verbose = FALSE)

Arguments

x_cols

tidyselect specification of a set of columns defining objects

y_cols

tidyselect specification of a set of columns defining objects
