rmix: Mix random samples

In ssokolen/metcourse: Tools for Metabolic Time-course Data

Mix random samples

Description

Generates a random sample by mixing two distributions.

Usage

rmix(n, p, rdist1, rdist2)

Arguments

n	Number of samples to draw.
p	Proportion of samples to draw from rdist1 vs rdist2 (true proportion taken as the fraction of random uniform values smaller than p).
rdist1	User-defined function for generating random samples (must take n as only argument).
rdist2	User-defined function for generating random samples (must take n as only argument).

Value

A vector of n values sampled from rdist1 and rdis2.

Examples

rdist1 <- function(n) {rnorm(n, -1, 0.5)}
rdist2 <- function(n) {rnorm(n,  1, 0.5)}
out <- rmix(10000, 0.3, rdist1, rdist2)
print(summary(out))
hist(out, 20, xlim = c(-2, 2), probability = TRUE, 
     main = '', xlab = 'Random variable value')
