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 ...
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...

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 ...
