mvrnorm2 {PKPDsim}

More powerful multivariate normal sampling function

Description

Besides standard multivariate normal sampling (mvrnorm), allows exponential multivariate normal and quasi-random multivariate normal (using the randtoolbox) all using the same interface.

Usage

mvrnorm2(n, mu, Sigma, exponential = FALSE, sequence = NULL, ...)

Arguments

n

number of samples

mu

mean

Sigma

covariance matrix

exponential

exponential distribution (i.e. multiply mu by exponential of sampled numbers)

sequence

any sequence available in the randtoolbox, e.g. 'halton', or 'sobol'

...

parameters passed to mvrnorm or randtoolbox sequence generator

Value

Multivariate normal samples
