In adibender/rFtools: Tools for the analysis of Random Forests (and cforest)

Description

Returns the layer of every (not terminal) node in the forest, the root having layer 1.

Usage

getLayerForest(ancestryForestObj = list())

Arguments

ancestryForestObj

A list as it is returned by getAncestryForest.

Details

Applies getLayerTree to every list element.

Value

A list of length ntree. Each list element contains a vector where the single elements indicate the layer of the according (not terminal) nodes.

Examples

## data
YX <- simulateSNPdata(seed = 123)

## forest
rF <- randomForest(x = YX[ , -1], y = YX[ , 1], keep.forest = TRUE, 
		keep.inbag = TRUE, importance = TRUE, ntree = 500)

## ancestry		
aF <- getAncestryForest(rF)

## layer
lF <- getLayerForest(aF) 
length(lF) == rF$ntree
lF[[1]] ## layers of not terminal nodes for the first tree
