Sample Sequences from a Fitted Context Tree

Usage

generate_sequences(tree, n = 5L, length = 10L, start = NULL)

Arguments

tree: A transitiontrees.
n: Integer. Number of sequences to sample.
length: Integer. Length of each sampled sequence.
start: NULL or character vector. If NULL (default), each sequence starts from the root marginal; otherwise must have length n and supply the first state of each sequence.

Value

A character matrix of dimension n x length.

Examples

# \donttest{
seqs <- replicate(50, sample(c("A","B","C"), 12, replace = TRUE),
                  simplify = FALSE)
tree <- context_tree(seqs, max_depth = 3)
generate_sequences(tree, n = 5, length = 10)
