In RapidMiner 5, can I input plain text data, separted by white space?
In RapidMiner 4.6 it is easy to do this.
Also, is it possibe after I input all the data with 40 attributes, I can choose use 20 attributes to build a model, then next time, I might use 15 attributes. Is it a way to do it without re-inputing data?

Hi,
this time haddock has been right only for 50%
It's yes and yes.
In RapidMiner 5.0 there's an operator called work on subset that let's you select only a subset of the attributes. You might put two of this operators into one process and connect the output of the input operator two both inputs. If you connect the second you will be asked how to proceed and if you chose to insert an IOMultiplier, the exampleSet is doubled by a new operator.
