split_frequencies: Get summaries of which features the forest split on

Description

Get summaries of which features the forest split on

Usage

split_frequencies(forest, max.depth = 4)

Arguments

forest

The trained forest.

max.depth

Maximum depth of splits to consider.

Value

A matrix of split depth by feature index, where each value is the number of times the feature was split on at that depth.

Examples

# NOT RUN {
# Train a quantile forest.
n = 50; p = 10
X = matrix(rnorm(n*p), n, p)
Y = X[,1] * rnorm(n)
q.forest = quantile_forest(X, Y, quantiles=c(0.1, 0.5, 0.9))

# Calculate the split frequencies for this forest.
split_frequencies(q.forest)

# }
