data a.student
infile ‘e:\data\student.txt’
input name height weight
以上程序将目录“e:\data\”下的文本文件“student.txt”中的数据输入数据集student中,该数据集存放于目录“e:\data\”下。
(2)直接输入方式
数据量较少或 *** 作者意志力坚强的情况下采用此种输入方式,在data语句之后写入如下语句:
input变量名1变量名2 …变量名n
datalines(在以前的版本下为cards,新版本下两者可通用)
… … … …(数据行)
… … … …(数据行)
… … … …(数据行)
datalines语句用于直接输入数据,标志着数据块的开始。
注意:这里的数据行中数据之间以空格分隔,当然也可以其它东东如逗号等来分隔,这里大家先以空格来分隔好了。因为不同的分隔方式下input语句要采取相应的控制选项,这些我们以后再讨论,这里我们还是省省力气吧。另外数据行输完后不能像其它语句那样直接在后面加上分号,而要另起一行输入分号,这样SAS才认为这是在输入原始数据而不是在搞别的什么。
SPSS编程
通过菜单选择:File-New-Syntax,打开语句编辑窗口(SyntaxEditor)编写程序(也可以在word或其他文本编辑软件中编写,通过复制粘贴方式将程序粘贴到此窗口),若已建立程序,可通过File--+Open--+Syntax直接打开。
