Rtreemix (version 1.34.0)

get.tree.levels: Function for constructing level vectors

Description

Function that assignes to each node the level at which that node is in a specific tree (tree.num) of the mutagenetic trees mixture model mixture. The start.val is the number assigned to the events pruned from the tree. This usually is the maximum depth of the tree with which the tree specified with tree.num will be compared.

Usage

get.tree.levels(mixture, tree.num, start.val)

Arguments

mixture

An object of the class RtreemixModel.

tree.num

A numeric specifying the tree component from mixture used for creating the level vector.

start.val

A numeric specifying the number assigned to the pruned events.

Value

The function returns a named numeric vector. Its length equals the number of genetic events in mixture minus one (for the initial null event which is always on level 0). The vector names correspond to the names of the genetic events and each vector component gives the level at which the respective event is in the num.tree tree of mixture.

Examples

## Generate two random RtreemixModel objects each with 3 components.
rand.mod <- generate(K = 3, no.events = 9, noise.tree = TRUE, prob =
c(0.2, 0.8))

## Get the tree levels of the 2nd component of the model rand.mod.
get.tree.levels(mixture = rand.mod, tree.num = 2, start.val = 10)
