Plot selected measures of importance of variables in a forest using ggpairs
plot_importance_ggpairs(importance_frame, measures = NULL, main = "Relations between measures of importance")
Arguments
| importance_frame | A result of using the function measure_importance() to a random forest or a randomForest object |
|---|---|
| measures | A character vector specifying the measures of importance to be used |
| main | A string to be used as title of the plot |
Value
A ggplot object
Examples
forest <- randomForest::randomForest(Species ~ ., data = iris, localImp = TRUE, ntree = 200) frame <- measure_importance(forest, measures = c("mean_min_depth", "times_a_root")) plot_importance_ggpairs(frame, measures = c("mean_min_depth", "times_a_root"))
