Delete是用来删除记录的

data crackman;
input x y z m n@;
cards;
1 2 3 . 6
3 . 6 7 9
3 4 7 8 9
;
run;
proc transpose data=crackman out=a;
var _all_;
run;
data a;
set a;
array col col1-col3;
do over col;
if col=. then delete;
end;
run;
proc transpose data=a out=crackman(drop=_name_);
var col1-col3;
run;
或许是一个方法

找不到nmiss相关的具体的example, 不知道怎么用... go on

nmiss 是用来计算有数据缺失的变量的数量的...

data test;
  input a b;
  datalines;
1 2
. 5
. 4
2 .
3 4
. 8
;

proc transpose data=test out=a;
var _all_;
run;

proc sql noprint;
    select distinct _name_ into :dropvar separated by " "
         from a
         where nmiss(col1,col2,col3,col4,col5,col6)=3;
quit;

data result;
    set test;
        drop &dropvar;
run;
