"Accessing parameter values by macros"
Contributor II
I want to write some parameter values into the filename string of my output file, e.g. when iterating over the number of clusters in k-Means I want the output files "output_2.arff", "output_3.arff", etc.
Setting the filename to "output_%{operator.KMeans.parameter.k}.arff" does not work.
I found a workaround here: http://rapid-i.com/rapidforum/index.php/topic,801.0.html
A process log is used to read current parameter values, is then converted to an example set and by data macro definition a macro holding the appropriate value is defined.
Isn't there a simpler way to access current parameter values via macros?

yes there is simpler solution to that: Insert a SingleMacroDefinition and define your macro there. Then use the ParameterCloner to copy the parameterValue you want in your macro into the value parameter of the SingleMacroDefinition operator. Et voila!
