get_distance_values: 'get_distance_values' calculated tree based distance values...

In imbs-hl/timbR: Tree interpretation methods based on ranger

get_distance_values calculated tree based distance values for a single tree or random forest built with ranger. Returned distance values still need to be aggregated, e.g. with get_distance_score.R. function to get distance values that returns matrix with distance values

Description

get_distance_values calculated tree based distance values for a single tree or random forest built with ranger. Returned distance values still need to be aggregated, e.g. with get_distance_score.R. function to get distance values that returns matrix with distance values

Usage

get_distance_values(rf, metric = metric, test_data = NULL)

Arguments

rf	Object of class ranger used with write.forest = TRUE.
metric	Specification of distance (dissimilarity) metric. Available are "splitting variables", "weighted splitting variables", and "prediction".
test_data	Additional data set comparable to the data set rf was build on. Only needed for metric "prediction".

Value

matrix of values for distance calculation (cols = trees)
