In pseudocode it would likely look something like this: %let chars_to_replace = '-,+*!.=^!'; *Gives a list of special characters to search for and replace %let char_to_replace_with = '|'; *Gives the character I
ANYNAME Function Searches a character string for a character that is valid in a SAS variable name under VALIDVARNAME=V7, and returns the first position at which that character is found. ANYPRINT Function Searches a character string for a printable character, and returns the first position at whi...
The LENGTH function returns an integer that represents the position of the rightmost non-blank character in string. If the value of string is blank, LENGTH returns a value of 1. If string is a numeric constant, variable, or expression_r(either initialized...
TRANWRD函数可以把字符串里的指定字符转换成另外一指定字符。 用法:TRANWRD(Source, From, To),Replace from character sting in source with to character string。语句TRANWRD(pct,’( ‘,’ (‘),把pct=“( 10.1%)”变成pct=“ (10.1%)”,也就是把...

string and numeric variable conversion 在R中,转成字符串用as.character(),转成数值型则是as.numeric() 在SAS中,大部分转化是用out以及input实现的,以sashelp的class数据集为例,可以看到Age,Height,Weight是数值型(可以根据变量值是否右对齐来判断),然后用put将其从数值型转化为字符串型 ...
