Re: [程式] SAS proc means 垂直加總
※ 引述《andersonhaha (好山好水 多健康)》之銘言：
: id condition 1997 1998 1999 2010
: 1 A 0 0 0 1
: 1 B 0 1 1 1
: 1 C 0 0 2 2
: 加總 0 1 3 4
: 2 A
: 2 B .. .. .. .. ..
: [程式範例]:
: proc means data=a sum;
: class id condition;
: var 1997-2010
: output out=b; run; 是這樣嗎？SAS好像跑不太動..(windows full)..
: 謝謝指教！！
data step1;
set demo_data;
forsort='1';
format condition $char100.;
run;
PROC SQL;
CREATE TABLE step2 AS
SELECT distinct id,
"總合" as condition,
sum('1997'n) as '1997'n,
sum('1998'n) as '1998'n,
sum('1999'n) as '1999'n,
sum('2000'n) as '2000'n,
'2' as forsort
FROM WORK.DEMO_DATA
group by id;
QUIT;
data final;
set step1 step2;
run;
PROC SORT DATA= final OUT= final; BY id forsort;
RUN;
順便請問一下要怎樣在data set裡面改欄位長度
