[Solved]Filter

javemar

Hello

I has been testing rapidminer, but I don't understand why the below process dont work. My process is supposed  generate one data, then, I set  a macro with the same value that I did on the before operator. Then,  I make a filter with the value of the macro. I expected to get one value in the result overview, but I got anything.

Could anybody help me?

Hi,

you need to write your macro value without quotation marks.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.2.007">

    <input/>
    <output/>

        <list key="attribute_values">
          <parameter key="correo" value="&quot;uno&quot;"/>
        </list>
        <list key="set_additional_roles"/>
      </operator>
      <operator activated="true" class="set_macro" compatibility="5.2.007" expanded="true" height="76" name="Set Macro" width="90" x="179" y="120">

        <parameter key="parameter_string" value="correo=%{valor}"/>
      </operator>
      <connect from_op="Generate Data by User Specification" from_port="output" to_op="Set Macro" to_port="through 1"/>
      <connect from_op="Set Macro" from_port="through 1" to_op="Filter Examples" to_port="example set input"/>
