mydata[order(mydata$value,decreasing=T),] #根据value降序排列 以上这种方式通过基于数据框自身的规则,完成了排序工作(实际上是一种布尔索引),但是不够优雅,写了繁琐的变量名,而且只能根据一个字段来排序。 数据框排序-arrange arrange函数的存在实在是R语言排序大杀器。 library(dplyr) mydata%>%plyr::arrange...
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 ...
df1=df1.set_index('id') #设置索引列 df1.sort_index() #使用索引进行排序 df1.sort_index(ascending=False) #使用索引列降序排列 --- 本节小结: --- 排序函数: R语言: 向量: sort order rank 数据框: arrange Python: 列表与字典: sort sorted 数据框: .sort_index .sort_value...
Sort a data frame rows in ascending order (from low to high) using the R function arrange() [dplyr package] Sort rows in descending order (from high to low) using arrange() in combination with the function desc() [dplyrpackage] library(tidyverse) my_data <- as_tibble(iris) my_data ...

arrange [dplyr] – Order data frames and tibbles. attach – Give access to variables of a data.frame. attr – Return or set a specific attribute of a data object. attributes – Return or set all attributes of a data object. as.Date – Convert character strings to Date class. ...
The system automatically assigns a rule ID to the new rule and arrange the rule as the last one. You can run the display acl ipv6 command to view whether the rule ID to be specified already exists. When an advanced ACL6 is configured, the fragment parameter cannot be used together with...
