Generate a Transmission Tree

Description

Creates a transmission tree with a specified number of cases and branches per case. The tree can be generated with fixed or Poisson-distributed branching factors.

Usage

make_tree(n_cases, R = 2, stochastic = FALSE, plot = FALSE)

Arguments

`n_cases`	Integer. The total number of cases (nodes) in the tree.
`R`	Integer. The fixed number of branches per case when `stochastic` is `FALSE`, or the mean of the Poisson distribution when `stochastic` is `TRUE`.
`stochastic`	Logical. If `TRUE`, the number of branches per case is sampled from a Poisson distribution with mean `R`. Default is `FALSE`.
`plot`	Logical. If `TRUE`, the function will plot the generated tree. Default is `FALSE`.

Value

An igraph object representing the transmission tree.

Examples

# Generate a deterministic transmission tree
deterministic_tree <- make_tree(n_cases = 15, R = 2, stochastic = FALSE, plot = TRUE)

# Generate a stochastic transmission tree
random_tree <- make_tree(n_cases = 15, R = 2, stochastic = TRUE, plot = TRUE)
