Description

This is a convenient wrapper that uses filter[] and min_rank[] to select the top or bottom entries in each group, ordered by wt.

Examples

# NOT RUN { df % top_n[2] # Negative values select bottom from group. Note that we get more # than 2 values here because there's a tie: top_n[] either takes # all rows with a value, or none. df %>% top_n[-2] if [require["Lahman"]] { # Find 10 players with most games # A little nicer with %>% tbl_df[Batting] %>% group_by[playerID] %>% tally[G] %>% top_n[10] # Find year with most games for each player tbl_df[Batting] %>% group_by[playerID] %>% top_n[1, G] } # }
