Character 字符型变量,也包括Text(文本)或String(字符串)。这种类型的变量不能用于运算,并且会区分大小写。如果你对性别变量分组,那么M和m会被分成不同的组。SAS默认会把数据看成数字型变量,所以必须要手动把诸如ID号之类的数字形式的变量设置成字符型变量。 Date 日期型变量。要输入SAS的数据集中的日期变量可能会...
@charactervariable 首先确定字符变量所取值(即字符串)在输入行的位置,然后把指针移到这个字符串之后的第一个非空格列。 @(characterexpression) 先确定字符表达式值的位置,然后移指针到其后第一个非空格列。 @+n 把指针向右移动n列。如: INPUT @20 AGE 2. +4 WEIGHT; @+...
sas 合并不了,提示错误为:ERROR: Variable ___1 has been defined as both character and numeric. 答案 这是因为你的合并变量在两个来源数据集中定义的类型不一致,一个是字符型,另外一个是数值型.需要重新定义类型,比如说用format语句.相关推荐 1sas 合并不了,提示错误为:ERROR: Variable ___1 has been ...

answer:?? b To permanently associate a format with a variable, you use the FORMAT statement in a DATA step. You can use the FORMAT procedure to create a user-defined format. You use the INPUT function to convert character data values to numeric values with an informat. You use the INPUT...
Correct answer: d By default, columns for character variables are the same as the variable's length, and columns 46 for numeric variables have a width of 9. So these headings split this way by default. 10. Suppose you want to create a report using both character and numeric variables. ...
The _ERROR_ variable contains the number of the observation that caused the data error.答案: C本题知识点:WHERE语句类似第 15 50、题。Q 19The SAS data set WORK.ONE contains a numeric variable named Num and a character variable named Char:WORK.ONENumChar- -1 233 231 77The following SAS...
