Question

我在SAS有一张桌子，

Group1   Group2  type
  1.1     1.4     value
  0.5     0.4     value
  5        6      percent
  4        10     percent

我想把它分成四列，如下所示：

Group1_value  Group1_percent Group2_value Group2_percent
 1.1             5               1.4         6
 0.5             4               0.4         10

Answer 1

简便方法是PROC SQL

这会很快而且很脏。

data have;
input group_1 group_2 type $;
cards;
1.1 1.4 value
0.5 0.4 value
5   6   percent
4   10  percent
;
run;

proc sql;
create table g1v as
select distinct group_1 as group1_value
from have
where type = 'value'
order by group_1 desc
;
create table g1p as
select distinct group_1 as group1_percent
from have
where type = 'percent'
order by group_1 desc
;
create table g2v as
select distinct group_2 as group2_value
from have
where type = 'value'
order by group_2 desc
;
create table g2p as
select distinct group_2 as group2_percent
from have
where type = 'percent'
order by group_2
;
data final;
merge g1v g1p g2v g2p;
run;

其他方法是使用宏工具（但如果type中只有两个值，则可能没有必要）。

Answer 2

使用DATA Step重塑数据后，您可以使用Proc TRANPOSE。

data have;
input 
Group1   Group2  type $; datalines;
  1.1     1.4     value
  0.5     0.4     value
  5        6      percent
  4        10     percent
run;

* reshape data for Proc TRANSPOSE;

data forTranspose;
  set have;
  by type notsorted;
  if first.type then seq = 1; else seq + 1;

  name = 'Group1_' || type;
  value = group1;
  output;

  name = 'Group2_' || type;
  value = group2;
  output;
run;

proc sort data=forTranspose;
  by seq;
run;

proc transpose data=forTranspose out=want;
  by seq;
  id name;
  var value;
run;

在sas中将两列拆分为四列
