.data

a tibble

group_data() return a tibble with one row per group. The last column, always called .rows is a list of integer vectors indicating the rows for each group. If .data is a grouped data frame the first columns are the grouping variables. group_rows() just returns the list of indices.

Other grouping functions: group_by_all, group_by, group_indices, group_size, groups

df <- tibble(x = c(1,1,2,2))

# one row
group_data(df)
group_rows(df)

# 2 rows, one for each group
group_by(df,x) %>% group_data()
group_by(df,x) %>% group_rows()
