Hi
There is a gap between plots (white spaces) when I draw the boxplot. I want
to reduce the spaces between the plots so that the boxplot takes a small
space. When I just adjust "boxwex" values, the length of individual plots
increases/decreases but the white spaces is still there.

Hello everyone
I am using nested resampling in caret (5-fold outer and bootstrap inner
resampling) and by default, it shows the "Accuracy" metric. How can I use
it for the ROC/AUC metric?

I posted it for the second time as I didn't get any response from group

I cannot run the "ranger" model with caret. I am only using the farff and

Okay, thank you. I will do that.

I am using xgboost hyperparameter tuning for the value of rmse. I used the
following method which returns two values ; mean which is like - 1200.12
and Best value like - 960. I guess the first value is average value and the
second is the best rmse value returned by the algorithm.
Now if we have to
How the hyperparameter settings via adaptive resampling is different from
the one obtained from grid search or random search? Both grid and random
searches provide best parameters values and the same is achieved using
adaptive resampling.
