1 row_number函数 R语言中的row_number函数与sql中的row_number函数相同,对group_by后面字段进行分组,按照order_by后面字段排序,生成一个连续不重复的编码,对每个客户按照购买时间升序排序编码: 输出结果与sql输出结果有一点不同:R语言中输出结果的顺序与原始数据的顺序一致,而sql中是按照购买时间的先后顺序输出的,若...

base::order(): order returns a permutation which rearranges its first argument into ascending or descending order, breaking ties by further arguments.[3] 总结:order是按照其元素值的大小对向量进行重新排序,并返回其索引。 巧用order,对数据框进行排序 dt = data.frame(a=c(3,5,1,2,2), b=c(7...
sort(vec1) # ascending sort 升序 sort(vec1, decreasing = TRUE) # Descending sort 降序 1. 2. 或者 vec1[order(vec1)] # ascending sort vec1[rev(order(vec1))] # descending sort 1. 2. 自定义向量排列 seq(1, 10, by = 2) # diff between adj elements is 2 相邻元素差为2 ...
