SAS 数据格式化(反向 proc 转置?) [英] SAS Data formatting (reverse proc transpose?)

问题描述

    Q1  Q2  Q3   Q4
A   1   2   3   4
B   1   2   3   4
C   1   2   3   
D   1   2       
E   1   2   3   4

我有上面的数据，想将数据导入并重塑为如下所示:

I have data like above and would like to import and reshape the data into what it looks like below:

    Qtr var1
A   Q1  1
A   Q2  2
A   Q3  3
A   Q4  4
B   Q1  1
B   Q2  2
B   Q3  3
B   Q4  4
C   Q1  1
C   Q2  2
C   Q3  3
D   Q1  1
D   Q2  2
E   Q1  1
E   Q2  2
E   Q3  3
E   Q4  4

这似乎是一个proc transpose"，但它是相反的.

It seems like a 'proc transpose' but it's reversed.

请帮忙！

推荐答案

为什么不坚持使用 PROC TRANSPOSE.它可以从宽到长，也可以从长到宽.

Why not stick with PROC TRANSPOSE. It can do wide to long as well as long to wide.

data have;
input ID $ Q1  Q2  Q3   Q4;
datalines;
A   1   2   3   4
B   1   2   3   4
C   1   2   3   .
D   1   2   .   . 
E   1   2   3   4

proc transpose data=have out=want name=Qtr;
by ID;
