210061  ATLANTIC GENERAL HOSPITAL   MD  10.8

我想根据死亡率列对DF进行排序，然后按照医院列的字母顺序处理关系

我厌倦了使用不同的排序函数，比如

sorted <- work[order(work$Mortality,work$Hosptial),]

但最终的结果是错误的。 我得到的结果是

Hosptial    State   Mortality
CALVERT MEMORIAL HOSPITAL   MD  10.1
HOWARD COUNTY GENERAL HOSPITAL  MD  10.1
JOHNS HOPKINS HOSPITAL, THE MD  10.2
LAUREL REGIONAL MEDICAL CENTER  MD  10.6

MARYLAND GENERAL  HOSPITAL  MD  10.8
DOCTORS'  COMMUNITY HOSPITAL    MD  11
FORT WASHINGTON HOSPITAL    MD  11
WASHINGTON ADVENTIST HOSPITAL   MD  11

获取2个参数的函数：

状态（检查原始CSV数据）

心脏病发作/热衰竭/肺炎

我的完整代码是

best <- function(states,outcomes)  
{  

    #patterns is obtained to use them in the regex function 
    patterns<-paste("^Hospital.*",outcomes, sep="")
     Readcsv<-read.csv("outcome-of-care-measures.csv", check.names = F)
    columnname<-colnames(Readcsv)
    #regex operation going on
    regex1<-grep(patterns,columnname,ignore.case=TRUE, value = T)
    #another regex operation
    Extracted<-grep("Mortality",regex1,ignore.case=TRUE, value = T)
    #extract dataframe based on the state and final extracted column name using the regex function
    dfe<-subset(Readcsv, Readcsv$State == states & Readcsv[[Extracted]]!="Not Available")
     #create a vector
    b<-c("Hospital Name","State", Extracted)
    #extract only those columns seen in the vector
    work<-dfe[,b]
    #change column name
    colnames(work)<-c("Hosptial","State","Mortality")
    # stuck after this point
    Ascorder<-work[with(work, order(Mortality, Hosptial)),]

}

best您可以为此使用dplyr：

require(dplyr)
work <- work %>%
    arrange(Mortality, Hospital)

require（dplyr）
工作百分比
安排（死亡率、医院）

我无法测试它，因为您没有给出数据的可复制示例，但它应该可以做到这一点。
当我尝试将其直接应用于过滤数据帧时，排序顺序不正确，但当我将过滤后的DF导出到CSV中并再次读取并实现该功能时，它运行良好。但不管怎样，它现在起作用了。谢谢你的解决方案。
require(dplyr)
work <- work %>%
    arrange(Mortality, Hospital)
