我是SAS的新手，我遇到了问题。我有这样的数据集：
Dataset_idchemo
我想用0 if Chemo = NonTreated else 1创建一个新的虚拟变量，但idk为什么我不能，结果是一个只有零的列和一堆警告，如" Invalid numeric data, 'Treated' , at line 74 column 13."
我的代码是：
data new;
set readm;
chemio = 0;
if chemo =: 'Treated' then chemio = 1;
run;
谢谢！
PS：这是我的数据集，我不知道这是否是在这里添加它的正确方法，让我知道最好的方法是什么。
有四列Oss，它是观察的数量，id，event（0或1）和chemo（“已治疗”，“未经治疗”）
Oss id event chemo

答案 0 :(得分：2)
您的问题不在您提供的代码中，而是在它之前。您没有成功创建readm。为了表明这一点，请运行以下代码：
proc print data=readm (obs=9);
run;
（obs=只是将列表限制为9个观察值。）
不知何故，SAS必须通知您的第四栏是文本栏
你可能写过像
这样的东西data readm;
infile 'C:\<some path>\<some file>';
input Oss id event chemo;
run;
我会将其视为
data readm;
infile 'C:\<some path>\<some file>' truncover dsd dlm='09'x;
input Oss id event chemo $9.;
run;
在此
dcd指定您有分隔符dlm='09'x指定您的分隔符是标签truncover指定您不想阅读下一行以查找“化疗”的最后一个字符。下一行的字段如果这不是您问题的答案，请告诉我们您如何创建/导入readm，我们会看到我们可以做些什么。
免责声明：此代码未经过测试。如果它有错误，请通知我，我会调试它。
