I am trying to create a component where I can split an input table into two multi variable blocks (X and Y) for PLS analysis (using R node). I’ve found the multiple selection configuration but cant work out how to link to my input table. Anyone got any hints? Many thanks, Mark
Solved it. Create a component with a Column Filter Configuration feeding into a Reference Column splitter.
The next part of the puzzle solved. To define the X and Y I have joined the X and Y blocks using the Add Table to R. Y is the rframe and X is the knime.in. Then I use an R snippet to count the number of columns in Y then convert to a flow variable which feeds into the R learner node where the X and Y blocks can be defined for PLS or MLR model building.
