Hi there, So in my dataset I have variable ID which is repeated (only in name of it) for each participant. So for example ID=A-0-0082, it is repeated in rows due to fact that participant changed a (variable)job. So one row is A-0-0082 with job X and second row the same participant again A-0-0082 with job X, the next three rows are for next participant with id B-0-0011 with jobs X,Y,Z etc. So what i want to do is to select only rows from id (A-W-0-10-0-9999) <--- format of ID (A-W is a range, same for first number 0-10 range, same with third "value" 0-9999, what creates for example B-2-0012) with for example job X note: that i want to read all the rest variables like age, gender etc in new datasets. First time I have a such data and I don't know even how to start. Please, help me? is it even possible? I can't paste you dataset or code, sorry for that.
