Random sequences generation

Description

Generates random sequences.

Usage

1

Arguments

n

number of sequences to generate

length

sequences length

alphabet

the alphabet from which the sequences are generated

p

an optional vector of probabilities for the states in the alphabet. Must be of the same length as the alphabet. If not specified, equal probabilities are used.

Details

Each sequence is generated by choosing a set of random numbers (with min=1 and max=length of the alphabet) using the runif function. When the probability distribution is not specified, the uniform probability distribution giving same probability to each state is used to generate the sequences.

Value

a sequence object.
