Question

我最近将两个数据集与一个非常简单的Merge语句组合在一起。我正在使用ACS数据集和人口普查人口数据集。我需要后者的旗帜才能成为前者。当我合并时，地方变量（城镇/县，州）没有重复数据删除，因为一个数据集使用州缩写而另一个使用完整拼写：

   Obs GeoID           GeoName
    1  .            Abbeville County, SC    
    2  45001        Abbeville County, South Carolina

我需要更改Obs1的GeoName，使其等于Obs2

index功能会有效吗？或者我需要TRANWRD功能吗？感谢。

解决：

data _null_;
length geoName $100;
GeoName_C = scan(GeoName,1,',');
GeoName_S = scan(GeoName,-1,',');  *-1 scans from the right in case you could have commas in the city - check for this and adjust GeoName_C to include them if it is possible;
GeoName_S_F = stnamel(strip(GeoName_S));
GeoName = catx(',',GeoName_C,GeoName_S_F);
put _all_;
run;

Answer 1

我要做的是将城市与州分开，并使用SAS的内置功能stnamel将缩写转换为全名。

data _null_;
length geoName $100;
GeoName='Abbeville Road, SC';
GeoName_C = scan(GeoName,1,',');
GeoName_S = scan(GeoName,-1,',');  *-1 scans from the right in case you could have commas in the city - check for this and adjust GeoName_C to include them if it is possible;
GeoName_S_F = stnamel(strip(GeoName_S));
GeoName = catx(',',GeoName_C,GeoName_S_F);
put _all_;
run;

TRANWRD修复合并错误？
