R: Calculate which features the forest split on at each depth.

split_frequencies {grf} | R Documentation

## Calculate which features the forest split on at each depth.

### Description

Calculate which features the forest split on at each depth.

### 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)

    ## End(Not run)
