如何仅转置单列，保持一列相同？

Question

我如何这样转置？ 我知道完全转移它，但这个我不熟悉。

Answer 1

这应该做的工作：

data a;
  cust = "A";
  channels = 20;
  output;
  cust = "A";
  channels = 30;
  output;
  cust = "A";
  channels = 40;
  output;
  cust = "B";
  channels = 200;
  output;
  cust = "B";
  channels = 300;
  output;
  cust = "B";
  channels = 0;
  output;
run;

proc transpose data=a out=b;
  by cust;
  var channels;
run;
