Special Characters

This probably isn't a bug, but what special characters are not allowed in Rapid Miner attribute names? I spent several hours today debugging a script, only to discover that Rapid Miner doesn't process any attribute names with "%".  I already know that I can't use ".", but are there any other special cahracters that I need to be aware of?  I found that "-", "/", "(", ")" work OK, but I'm not sure of any other special characters I need to avoid using in attribute names.

Thanks...

    Hi,

    in general, the % sign should not be a problem. Some operators, however, will have problems, e.g. if you are using Generate Attributes. That operator will treat the percentage sign in a formula as operators instead of part of an attribute. If you want to be on the safe side, only use alpha-numerical characters and the underscore. Before displaying the results, there is no problem in renaming the attributes to nice user-friendly names.

    Best regards,
    Marius
