Builds a vector with ABO blood group

Returns a vector with ABO blood groups according to user defined frequencies

Usage

abo(n = 100, probs = c(0.4658, 0.0343, 0.077, 0.4229), seed.number = 123)

Arguments

n

An integer to define the length of the returned vector

probs

A vector with the probabilities for blood group A, AB, B and O (in this order). The sum of the probabilities must be equal to one.

seed.number

Seed for pseudo random number generator.

Value

A vector length n with ABO blood groups

Examples

abo(n = 100, probs = c(0.4658, 0.0343, 0.077, 0.4229), seed.number = 123)
