2. R arrange() Ascending OrderThe arrange() function in R, provided by the dplyr package, sorts the rows of a data frame by the values of specified columns. By default, it sorts in ascending order, but it can also sort in descending order. To use the arrange() function, you need ...

之前说过,使用管道函数连接的语句执行顺序和书写顺序一致,上面语句可以理解为:1、使用group_by对指定的user_no字段分组;2、使用order_by函数对组内数据按照购买时间升序排列编码,增加一个新字段;3、使用arrange对指定的字段user_no和buy_date排序。 2 min_rank函数 ...
