Question

Oragne3中的频繁项目集小部件需要从“文件”小部件输入。包含“transactions”的文件应该是 basket ，如示例所示：

Bread, Milk
Bread, Diapers, Beer, Eggs
Milk, Diapers, Beer, Cola
Bread, Milk, Diapers, Beer
Bread, Milk, Diapers, Cola

但是我的文件实际上有一个带有用户ID的列和带有实际事务的第二列，如下所示：

XYZ001, "Bread, Milk"
XYZ002, "Bread, Diapers, Beer, Eggs"
XYZ003, "Milk, Diapers, Beer, Cola"
XYZ004, "Bread, Milk, Diapers, Beer"
XYZ005, "Bread, Milk, Diapers, Cola"

如何将事务（第二列）传递给频繁的项目集小部件？

Answer 1

像这样转换您的购物篮文件：

user=1, Bread, Milk
user=2, Bread, Diapers, Beer, Eggs
user=3, Milk, Diapers, Beer, Cola
user=4, Bread, Milk, Diapers, Beer
user=5, Bread, Milk, Diapers, Cola

然后做你想做的任何事情（即剥离）user列？

如何使用Orange3从CSV文件中的列中提取频繁项目集？
