make_dtree: Make dtree

In ben519/btree: Binary Tree Wrangling

Description

Make a dtree from one of two constructors:

• A vector of node Ids and parent node Ids or

• A vector of node Ids, left-child Ids, and right-child Ids

Usage

make_dtree(nodeIds, leftChildIds, rightChildIds, splitVars = NULL,
  splitVals = NULL, data = NULL)

Arguments

nodeIds	A vector of node Ids
leftChildIds	A vector of left-child node Ids
rightChildIds	A vector of right-child node Ids
parentNodeIds	A vector of parent node Ids

Details

Returns a dtree object

Examples

library(data.table)

make_dtree(nodeIds=c(1), leftChildIds=c(NA_integer_), rightChildIds=c(NA_integer_))
make_dtree(nodeIds=c(1), leftChildIds=c(2), rightChildIds=c(3), splitVars=c("foo"), splitVals=c(3.5))
make_dtree(nodeIds=c(1,2,3), leftChildIds=c(2,NA,NA), rightChildIds=c(3,NA,NA), splitVars=c("foo",NA,NA), splitVals=c(3.5,NA,NA))
