` and why you need pd.DataFrame.copy() all over the place.` Thanks for saying this! Also, in the past decade, the R data analysis/munging ecosystem has matured far more than the equivalent in Python. These days, writing (tabular) data transformation code in R is often far cleaner, clearer and less error prone than any other platform imo.
