proximityMatrixRanger: Get proximity matrix of an ranger object

In sipemu/similarity: Similarity Calculation

Description

Get proximity matrix of an ranger object

Usage

proximityMatrixRanger(x, y = NULL, rf)

Arguments

x	a new dataset
y	a second new dataset (Default: NULL)
rf	ranger object

Value

a dist or a matrix object with pairwise proximity of observations in x vs y (if not null)

Examples

## Not run: 
require(ranger)
rf <- ranger(Species ~ ., data = iris, num.trees = 5, write.forest = TRUE)
proximityMatrixRanger(x = iris[, -5], rf = rf)

set.seed(1234L)
learn <- sample(1:150, 100)
test <- (1:150)[-learn]
rf <- ranger(Species ~ ., data = iris[learn, ], num.trees = 5, write.forest = TRUE)
proximityMatrixRanger(x = iris[learn, -5], y = iris[test, -5], rf = rf)

## End(Not run)
