動作環境

RStudio @ Rollapp

names()を使ってみる。

> types<-c("human","android","Ferengi","Changeling")
> names(types)<-c("Kira","Data","Quark","Odo")
> types
      Kira       Data      Quark            Odo
    "human"  "android"  "Ferengi"  "Changeling"

名前付けしたものは以下のように取り出せる。

> types["Kira"]
   Kira
"human"
