在SAS中组合由分号分隔的两列

Question

我有以下数据集

ID  REGION  NUMTYPE
NY  us;ne   1015; 10x16
BO  us;ne   1015; 10x17
ID  nonus   1018

我想添加另一列＆＃34; REGION_NUMTYPE＆＃34;其中每行的区域和num类型的所有组合由＆＃34 ;;＆＃34;

分隔

ID  REGION  NUMTYPE             REGION_NUMTYPE
NY  us;ne   1015; 10x16     us1015; us10x16;ne1015;ne10x16
BO  us;ne   1015; 10x17     us1015; us10x17;ne1015;ne10x17
ID  nonus   1018                nonus1018

有一种简单的方法吗？非常感谢您的帮助

Answer 1

最简单的方法是双循环。

data want;
set have;
format Region_NumType $2000.; /*Modify size if needed*/


do i=1 to countw(region,";");
   do j=1 to countw(NumType,";");
      Region_NumType = cats(Region_NumType,scan(region,i,";"),scan(NumType,j,";"),";");
   end;
end;

run;
