That line will not generate the warning you cited but it will generate a numeric to character conversion. The warning is probably from some other part of the code where you are trying to use WHOSHCKO as if it was a number. For example by trying to use it in an expression or assign it...
One task is to change raw data into standard SDTM variable, such as if CPEVENT=”Treatment and Observation Period (Day1)” then VISIT=“Day 1”, or if CPEVENT=”Day 1” then VISITNUM=2001. Another commom task is value conversion between stan...
There remains, however, the danger of data being lost in the conversion process. This type of error is most likely to occur in cases of character-to-numeric variable conversion, most especially when the user does not fully understand the data contained in the data set. This paper will ...

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 ...
Most of these macros enable you to determine quickly the type of a character (whether it is alphabetic, numeric, punctuation, and so on). These macros refer to an external array that is indexed by the character itself, so they are generally much faster than functions that check the ...
