R內建的資料集datasets

R內建了一些資料集(datasets),用下面指令可以看:
  • data()
這個data()會輸出一個list,如下:
  • d <- data()
  • mode(d)
    "list"
  • names(d)
    "title"   "header"  "results" "footer"
  • str(d)
  • r <- as.data.frame(d$results)
  • write.csv(r, file="datasets.csv")
最後個指令會輸出一個datasets.csv的檔案,用excel打開,列出了104個資料集:
