(FDB) FDELETE Deletes an external file or an empty directory FEXIST Verifies the existence of an external file associated with a fileref and returns a value FGET Copies data from the File Data Buffer (FDB) into a variable and returns a value FILEEXIST Verifies the existence of an external...
%SYSFUNC(function(argument(s))<, format>))宏函数用于调用SAS函数或者使用FCMP过程步创建的自定义函数,还可以将结果按照指定格式输出 其他宏函数 %SYSGET(environment-variable)宏函数用于获取当前操作系统的环境变量的取值 %SYSPROD(product)函数用于判断在当前的SAS环境中,指定的SAS产品是否有License。若有相应许可,...
可以依照作用时间将上述quoting function分成两类:compliation function和execution function。前者的mask作用发生在编译期间,后者发生在运行期间。关于编译和运行的概念,这里不深入讨论了,仅提供一个例子: %macro getMaxVal(indata, invar); /* returns maxium value of a variable from a dataset*/ %if %symexist(...
A DATA step is used to split DE VELOP into TRAIN and VALIDATE. The variable U is created using the RANUNI function, which generates pseudo-random numbers from a uniform distribution on the interval (0,1). The RANUNI function argument is an initialization seed. Using a particular number, grea...
The following External Files function is new: DCREATE creates an external directory. The following macro functions are new: SYMEXIST indicates the existence of a macro variable. SYMGLOBL indicates whether a macro variable has global scope in the DATA step during DATA step execution. SYMLOCAL ...
SAS—第四讲: Editing a SAS data set by Data step 第四讲：SAS Data步和SAS数据集编辑 建立SAS数据集之后，需要对数据集进行必要的编辑。如删除一些变量或观测、产生新变量等等。利用SAS的DATA步，通过编程可以灵活的对SAS数据集进行编辑。§4.1 SAS编程基础 1、SAS程序 SAS语句：由SAS关键词、SAS名字、...
Fixed-format data is text data in which each variable occupies a fixed-width column in the input data file. Column width, rather than a delimiter, gives the data its structure. You can import fixed-format data using the rxImport function. Optionally, fixed-format data might be associated wit...
