我們可建立一個新欄位 DRUG2 = COMPRESS (DRUG, ‘MGmg‘);/*利用COMPRESS function將 MG跟mg排除*/ 則DRUG2中將只剩下原先DRUG裡面數字的部分. 要是原先的DRUG裡面, 不只有MG (mg) 這個單位呢: DRUG 10mg 300IU/ML 3TABLET … 此時, 若要把每個單位逐一新增到如上面那個’欲排除’的清單中, 恐怕是很...

想仿命令行,所以定义了一个类,让一个String 对应一个 function,将两者输入list容器. 类中定义了 QString commandStr; void (MainWindow::*commandFun)(void);一个QString ,一个指向MainWindow类成员函数的指针.但是没想到在类中使用函数指针这么复杂. 一般情况,我们使用函数指针声明和引用都很简单明了.但是在类...
SAS: scan函数的修饰语(modifier)说明,另外类比compress function;countw function和countc函数与scan函数的用法比较 SCAN(string, count <, character-list <, modifier>>) count为负,从右往左数。或者使用b修饰语,将从右向左; character-list,默认如果超过一个字符,则每个字符都是一个分隔符。如果使用“K”...
Most SAS(R) programmers rely on the COMPRESS function for cleaning up troublesome string data. The many uses of the third `modifier' argument, added in Version 9, may not be as familiar. This paper will present a quick summary of the options available and examples of their use. It will ...
Hello I use SAS EG and I'm wondering if there is a way to compress this kind of code, so I don't have to write 100 rows. If Columns 1 to 100 are together in the data, then if you wanted to keep those columns you could do keep Column1--Column100, is there something simil...
integer in the range of -1 to 9. The higher the value, the greater the amount of compression - resulting in smaller files but a longer time to create them. IfxdfCompressionLevelis set to 0, there will be no compression and files will be compatible with the 6.0 release of Revolution R...
