解壓下載的數據到:E:\R\R-beginer-guide\data\RBook數據庫
在R控制檯執行:ide
Squid <- read.table(file = "E:/R/R-beginer-guide/data/RBook/squid.txt",header=TRUE) Squid Sample Year Month Location Sex GSI 1 1 1 1 1 2 10.4432 2 2 1 1 3 2 9.8331 3 3 1 1 1 2 9.7356 4 4 1 1 1 2 9.3107 5 5 1 1 1 2 8.9926 6 6 1 1 1 2 8.7707 7 7 1 1 1 2 8.2576 8 8 1 1 3 2 7.4045 9 9 1 1 3 2 7.2156 10 10 1 2 1 2 6.8372 11 11 1 1 1 2 6.3882 12 12 1 6 1 2 6.3672 13 13 1 2 1 2 6.2998 14 14 1 1 1 2 6.0726 .................. .................. ..................
省略其他數據函數
這個命令實現了把數據從squid.txt文件中讀取出來以數據框的形式存儲到Squid中ui
Squid <- read.table(file = "E:/R/R-beginer-guide/data/RBook/squid.txt",header=TRUE) #命令真正內容: Squid <- read.table(file = "E:/R/R-beginer-guide/data/RBook/squid.txt",header=TRUE,dec=".")
dec指定小數點是什麼。blog
技巧:io
經過setwd設置工做目錄執行read.table函數事就不須要指定目錄了。table
scan也能夠導入數據不過read.table是將數據導入到數據框中,而scan是將數據導入到矩陣中。class
從其餘統計軟件中導入和從數據庫導入數據省略。沒條件實驗。gui
