R 拆分EXCEL成多个文件

setwd("C:/Rworkfile")
install.packages("readxl")
library(readxl)
 
www<-read_excel("www.xls")
www
 
table(www[,5])
 
a1=names(table(www$县编码))
a2=rep("XXXXXXXXXXXXXX",73)
a3=rep("XXXXXXXXXXXXXX",11)
 
for  (i in 1:73)
{
  a2[i]=as.matrix(www[www$县编码==a1[i],5])[1]
  a3[i]=as.matrix(www[www$县编码==a1[i],7])[1]
}
 
way= paste0("C:/Rworkfile/新建文件夹/",a3,"/",a2,".csv")
 
 
 
for  (i in 1:73)
{
  write.csv(www[www$县编码==a1[i],1:5],way[i])
}
