Issue with setting multiple values in a single macro using "OR" with Set Macros in RapidMiner

I am currently facing an issue with setting multiple values in a single macro using "OR" with Set Macros in RapidMiner.

I have tried using the following syntax to add multiple values to a macro:

{value1|value2|value3}
also few other syntax with and without the curly braces also

I would greatly appreciate it if anyone could share any insights or solutions regarding this issue.

    Hi,

    Can you share an example process of what you want to achieve?

    At least to me it's not clear where the values are coming from.

    Hi Jonas,

    I'll take an example, let's say to specify a Macro for a column named "Fruits", the purpose of the Macro is to select the values "apple", "banana", and "orange" from this column using the "OR" operator. However, I am facing difficulty in defining multiple values for a single macro.

    Regards,
    M

    Hi,

    So your Fruits column does look somewhat like this?

    Fruits
    apple
    orange
    banana
    pineapple
    tomato
    pear
    apple

    And your generated macro should contain "true" in this case?

    Or do you want to convert all matching Fruits into a "|" concatenated string like "apple|orange|banana|apple"?

    Greetings,

    Set macro operator
    macro name   |   values
    fruits               |   apple | banana | orange (defining multiple values in this single macro)

    then use this macros as %{fruits}

    You can copy the shared process xml from my previous post and paste it into the Process panel of RapidMiner Studio.


    Alternatively you could also use condition class custom_filters on Filter Examples

    It's not giving an output when I am doing the above filteration, its only giving it for "apple" not taking the value after OR
    operator

    Can you share your process xml? You can copy it from View → Show Panel → XML
