create_sequence {dsmmR}

Simulate a sequence for states of choice.

Description

This is a wrapper function around sample().

Usage

create_sequence(states, len = 5000, probs = NULL, seed = NULL)

Arguments

states

Character vector of unique values. If given the value "DNA" the values c("a", "c", "g", "t") are given instead.

len

Optional. Positive integer with the default value equal to 5000.

probs

Optional. Numeric vector with values interpreted as probabilities for each of the states in states. Default value is equal to 1 over the number of states given, for every state.

seed

Optional. Object specifying the initialization of the random number generator (see more in set.seed).

Value

A character sequence of length len.

Examples

# This is equal to having the argument `probs = c(1/4, 1/4, 1/4, 1/4)`.
rand_dna_seq <- create_sequence(states = "DNA")
table(rand_dna_seq)

random_letters <- sample(letters, size = 5, replace = FALSE)
rand_dna_seq2 <- create_sequence(
    states = random_letters,
    probs = c(0.6, 0.3, 0.05, 0.025, 0.025),
    len = 10000)
table(rand_dna_seq2)
