Separating data points

desireatem — Tue, 06 Feb 2018 03:55:21 GMT

Hello Madam/Sir,

I have this data set with variables Meds1-Meds10.

I have to create 10 other variables Medi1-Medi10 such that Medi1-Medi10 should have only the name of the medication, that is the first character variable. For example in obs 1, Meds1, the first data point is LIPITOR 10MG TABLET. This will be Lipitor. That is 10MG TABLET deleted. The case like in obs 3, Meds2, the BUDESONIDE will stay BUDESONIDE in the new name Medi2.

med1=scan(med1,1) and similar thing should work if it is only value. if you want to extract the value till the number then

data lll;
retain pattern;
 IF _N_ =1 THEN PATTERN = PRXPARSE ("/([^0-9]+)/"); 
input a $50.;
if prxmatch(pattern, a) then 
 call prxposn(pattern, 1, position, length);
 val = substr(a,position, length);
drop pattern position length; 
datalines;
my medicine 345
medicine 293
my medicine nice 76 this

So what do you want for the medi value from ALBUTEROL SULFATE HFA 90 MCG/ACTUATION AEROSOL INHALER?

If you only want ALBUTEROL then the scan function works fine. If you want more then much more work may be needed, such as defining how we know which part is actually needed for the longer compound names.
