Adding record to dataset

sasuser123123 — Fri, 20 Sep 2019 11:08:59 GMT

Hello!!
I want to add a new record to the existing dataset which shows average of two records of the data,the data is

PATIENT Res
101 78
101 72
102 80
102 90

So I need the out put like

Patient Res New_res
101 78 78
101 72 72
101 75
102 80 80
102 90 90
102 85

Could you please help me out.
And how to do.
Note:the res variable is character (how to do with out changing it to the numeric).

Thank you!

So New_res should always be the same as Res? And is New_res allowed to be numeric?

Yes.

This doesn't make much sense to me. However, if the Res variables should stau character (even though you request it to hold a numeric mean value), then do something like this

data have; 
input PATIENT Res $;
datalines;
101 78
101 72
102 80
102 90
;

data want(drop=s);
    do _N_=1 by 1 until (last.PATIENT);
        set have;
        by PATIENT;
        New_Res=input(Res, 8.);
        s+Res;
        output;
    end;
    New_Res=.;
    Res=put(s/_N_, 8. -l);
    output;
run;

Result:

PATIENT Res   NewREs
101     78    78
101     72    72
101     75    .
102     80    80
102     90    90
102     160   .

Thank you so much for your quick response

I'm extremely sorryyyyy..
The 75 and 85 values in my results are under New_res not under res.
And also I didn't get your progra. I'm trying it by using proc SQL but it shows an error 'The mean summary function requires a numeric argument'. Can we do it by using by proc SQL

Hi @sasuser123123

SQL is a good idea,


data have; 
input PATIENT Res $;
datalines;
101 78
101 72
102 80
102 90
;

proc sql;
create table want as
select *, input(res,best.) as New_res
from have 
union all
select PATIENT,' ' as Res,mean( input(res,best.)) as New_res
from have
group by PATIENT
order by patient,res desc;
quit;

Hi @sasuser123123 Honestly, it was your idea thanks to your thought process. My thought process didn't think of SQL. All I did was merely wrote the syntax which anybody can 🙂 Have a good one!

101 BS1 Diabp 80
101 BS1 RR 18
101 BS2 Sysbp 100
101 BS2 Diabp 60
101 BS2 RR 18
102 BS1 Sysbp 100
102 BS1 Diabp 60
102 BS1 RR 18
102 BS2 Sysbp 109
102 BS2 Diabp 50
102 BS2 RR 18
Now I'm trying to create one table which displays avg of results by TP and TEST per subject it means patient 101 has two records of SYSBP so I need avg of SYSBP...
I'm tried by using proc SQL but I didn't get output
Could you please solve this one

I saw your thread. If it's an ODS related question, I recommend asking Cynthia SAS, Reeza etc. They are experts and can guide you appropriately.
