I am using the mlr package in R to run the KNN algorithm. I am using tuneParams to search for the optimal k. When I run tuneParams the output shows the performance for each value of k. How can I save the performance for each k? The TuneResult object only has the optimal performance. I would like to use this to create a graph with the performance as a function of k.

1What have you tried to achieve this? Please include your code. – Ishaan Javali Nov 26 '18 at 01:56

I've tried using the ``sink`` function to save the output (which didn't work), but I was wondering if ``mlr`` stores it somewhere and I can access it. – mathnerd Nov 26 '18 at 02:00

Can you provide the code you're using please? – Lars Kotthoff Nov 26 '18 at 03:07

I figured it out, you can use ``TuneResult$opt.path$env$path`` – mathnerd Nov 26 '18 at 03:11

To complete the answer you found yourself: The best way to access all the settings that have been tried out:
as.data.frame(TuneResult$opt.path)
