Convert Quarterly data to Annual data

[Vanya16]

Hi Guys, what code can i use to convert quarterly data to Annual data; Here is a sample of the data. You will notice some quarters in some years are missing. But ideally i want to have annual figures summed up from quarterly figures per year per "Accper".  I want to have totals for TOR and TOE in two new columns computed from adding up the different figures from the different quarters. 

Stkcd	Accper	TOR	TOE	year	month	day	Quarter

[kiranv_]

may something like this might work.

proc sql;

select a.*, sum(TOR) as sum_tor, sum(TOE) as sum_toe from have

group by year, quarter;

quit;

[Kurt_Bremser]

proc sql;
create table want as
select year, sum(TOR) as TOR, sum(TOE) as TOE
from have
group by year;
quit;

or

proc summary data=have;
class year;
var TOR TOE;
output
  out=want (drop=_type_ _freq_)
  sum(TOR)=TOR
  sum(TOE)=TOE
;
run;
