Visualization is also a tool for exploration that may provide insights into the data that lead to new discoveries. It returns a permutation, so rather than order(x, params), you will want x[order(params),]. The sole difference between by and keyby is that keyby orders the results and creates a key that will allow faster subsetting (cf. Aggregates implemented in dplyr (lead, lag, nth_value, first_value, last_value) have an order_by argument. Example 1: R program to create dataframe with 2 columns and order based on particular columns in decreasing order.
