using amelia to deal with missing values

Hi there,

I’ve read the example https://www.knime.com/blog/how-to-deal-with-missing-values

for dealing with missing values with R amelia package.

I’m wondering if I can also in a cross validation this package at the same time on trainings and test data apply?

and how can I use the results further in Knime with e.g. Decision tree classifier ?

Thanks.

Best Regards,

N.
