- Need to view the list of variables in one dataset but not in the other dataset and add / delete variables, test with VAR and WITH if different names. If you want a list of BASE variables but not in the COMPARE
DATA new_dataset;SETdataset_1 dataset_n; DATA new_dataset;MERGEdataset_1 dataset_n;BYvariable_list; 纵向合并后,new_dataset 的行数等于每个数据集行数的加总。If one of the data sets has a variable not contained in the other data sets, then the observations from the other data sets will ha...
In reality for the example macro n that paper there was no need call that n_cntwrd macro at all. PROC SQL already counts for you into the macro variable SQLOBS. So to get the count and the list of variables in a dataset into macro variables just use: proc sql noprint; %let ...

1)Number of Variables in Common:相同的变量总数需要等于dataset中存在的变量总数。 2)Total Number of Observation:观测数相同且等于dataset中观测的总数(有的时候compare过程前可能进 行了筛选) 接下来,提供一个compare不一致的实例: 数据集1 数据集2 对两个dataset进行Proc compare,结果如下: 结果体现了两个data...
如果原始数据的不同变量之间是以至少一个空格作为分隔符的,那可以直接采用List方法将这些数据读入SAS。 List Input读数据非常方便,但也有很多局限性: (1) 不能跳过数据; (2) 所有的缺失值必须以点代替 (3) 字符型数据必须是不包含空格的,且长度不能超过8; ...
有些原始数据的变量之间没有空格或其它分隔符,因此这种文件不能以List形式对入SAS。但若不同变量值的都在每条记录的固定位置处,则能够依照Column 形式读入数据。Colunm读数据方法要求全部的数据均为字符型或者标准的数值型(数值中仅包含数字,小数点,正负号,或者是E,不包含逗号或日期型数据)。
The idea is to providebasic drawing function commandsfroman SG annotate data setthatcan be executedafter the plot has been created. The data set contains a list of columns with predetermined names that specify the function and the data or information needed for the function. ...
To usearray, I typearray, followed by the name of a program to do something to one variable, followed by a list of variables on which I want the program run. Using my other more-than-100 variable dataset, I could type . array add1 x1-x20 pop* d57 ...
the variables defined as theKEYandDATAcomponents of the hash objectare not automatically recognizedby the DATA step as are those in a dataset declared in a SET statement. 举例,如果不使用 length 进行声明 ,则报错: 这里如果不使用length语句,程序就会报错。
