给by参数传入多个列索引值时(用列表的方式),即可以对多个列进行排序。当第一列中有相等的数据时,依次按后面的列进行排序。ascending参数的用法与按多重索引排序一样。...对DataFrame排序可以对行排序(按行索引或按列),也可以对列排序(按列索引或按行),不过,对列排序会受数据类型的限制。对Series排序...
重要参数: priority = c("ascending","descending", "density", "random", "none") 默认为"ascending" 上升、升序; "descending" 降序、下降; 而"density"朝向上下两个方向; "random"和"none" 效果相似,为随机状; dodge.width可用于设置图形左右两侧空余区域,避免图形被绘图区域剪切。 总结: 该柱状图的主要还...
The current development version of data.table v1.9.3 has two new functions implemented, namely: setorder and setorderv, which does exactly what you require. These functions reorder the data.table by reference with the option to choose either ascending or descending order on each column to order...

data1%>%group_by(user_no)%>%mutate(nth_date=nth(buy_date,2,order_by=buy_date))%>%arrange(user_no,buy_date) 总结 本文介绍了R语言中的偏移窗口函数,在处理“错位“数据的时候可以使用偏移窗口函数,例如计算同比、环比、第一次消费时间、最近一次消费时间、每次消费时间间隔等。

newdata <- A[order(-A$x),] If you want ascending order then replace "-" with nothing. You can have something like newdata <- A[order(-A$x, A$y, -A$z),] where x and z are some columns in data.frame A. This means sort data.frame A by x descending, y ascending and...
SQL中窗口函数语句中over语句中两个关键词:partition by和order by,R语言中也有与之一一对应的函数: SQL中排名函数有4个:row_number()、rank()、dense_rank()和ntile(),R语言中也有4个排名函数与之对应,函数名也几乎相同: 函数使用 数据使用之前的数据: ...
