Plot a gg_ale_rfsrc interaction object

Source: R/plot.gg_ale_rfsrc.R
plot.gg_ale_interaction.Rd

Renders the second-order (interaction) ALE surface from gg_ale_rfsrc (when called with xvar2.name) as a ggplot2 heatmap. Values near zero mean the two predictors act additively over that region of their joint range; large positive or negative values mark where their combined effect departs from the sum of their individual main effects.
