One of the first lessons that SAS(R) programmers learn on the job is that numeric and character variables do not play well together, and that type mismatches are one of the more common source of errors in their-otherwise flawless-SAS programs. Luckily, converting variables from one type to ...
We know Format is a common function to convert date in SAS, such as,format aestdt date9.. What aboutProc Format? When and how should we use it? Case 1: Numeric to Character Presentation When data are coded in numerical, we would like to display it in characters in Frequency tables. S...
数组元素可以是已经存在的变量或不存在的变量,当数组元素是不存在的变量时,SAS会创建新变量。除了列出变量外,变量可以是关键 字_NUMERIC_、_CHARACTER_或_ALL_。 还可使用关键字_TEMPORARY_来创建临时数据元素。临时数据元素不会出现在输出数据集中,并且其值总是自动保持,而不会在D...

上面的代码尽管可以详细的查找是否存在缺失值以及定位缺失数据,但是在实际应用中更推荐以下由array数组和do循环构成的方法,由于采用了SAS特殊名称列表_numeric_和_character_所以无需修改,使用时将数据集名替换即可。以数据集patients为例,执行后将会在数据集中创建新变量"mvarlist",列出每条观测的缺失值清单,以便数据管理...
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 1 sas 合并不了,提示错误为:ERROR: Variable ___1 has ...
