Amen. The author takes the 4 operations below and discusses some 3-operation thing from category theory. Not worth it, and not as clear as dplyr. > But I kept looking at the relational operators in that table (PROJECTION, RENAME, GROUPBY, JOIN) and thinking: these feel related. They all change the schema of the dataframe. Is there a deeper relationship? |
