Import file for custom operation

Marvin_Jansen

Hey there,

I just started working with Rapidminer and want to write a custom operation in order to make some little changes in .csv files, which have a wrong format for Rapidminer. My approach is to import a csv file, edit it (just a few lines to delete) and use the edited file as my output, so that the "Read CSV" operation can use it as usual.

Up to now, the problem is that I don't know how to import files in my operation. Is there for example any option to include some sort of "Browse"- dialog like in the regular read operations?

 

Thanks,

Marvin

This might be a job for some groovy script. You can use the execute script operator for that. Or if python or R is more your flavor, then use one of those execute script operators

That really sounds less complicated, thank you!
