Create a scatterplot
Another useful plot for comparing models is the scatterplot, also known as the xy-plot. This plot shows you how similar the two models' performances are on different folds.
It's particularly useful for identifying if one model is consistently better than the other across all folds, or if there are situations when the inferior model produces better predictions on a particular subset of the data.

Pass the resamples object to the xyplot() function. Look at the resulting plot and note how similar the two models' predictions are (or are not) on the different folds. Be sure to specify which metric you want to plot.
