[問題] 從large list中將各類別存成各表
[問題類型]:
程式諮詢(我想用R 做某件事情，但是我不知道要怎麼用R 寫出來)
[軟體熟悉度]:
新手(在coursera修完兩門的新手，問些蠢問題請包涵）
[問題敘述]:
想將ㄧ大表格，依照類別分割並另存各表。
依照各州再依照死亡率、出生率等排序，想分別存成'每州'的表格。主要目標是想抓各州
死亡率最低的醫院、出生率最高的醫院、出生率第五的醫院等
目前做法做到卡關，手機發文概略寫一下，排版亂請見諒
感謝幫助
[程式範例]:
X<-read.csv()
subx<-split(x,x$state)
這時會存成含54個元素但各元素row不同的large list,沒去na值
然後就不知道怎麼寫了，知道要迴圈，但不知道怎麼分割元素另存
For ( I in x$state){
list[i]<-lappy(subx[i］,........
}
[環境敘述]:
Rsdutio3.1.2
[關鍵字]:
選擇性，也許未來有用
