Simulate concentration changes

Description

Simulates relative (fractional) changes in metabolite concentrations using a mixture of beta distributions.

Usage

simulate_rel_change(n, par1, par2 = NULL, p = 0.5, con = NULL)

Arguments

`n`	Number of samples to draw.
`par1`	Parameters (alpha, beta) for first distribution.
`par2`	Optional parameters (alpha, beta) for second distribution.
`p`	Proportion of samples to draw using `par1` vs. `par2`. Note, `p` is ignored if `par2` is not specified.
`con`	Optional vector of lower and upper constraints on generated samples.

Value

A vector of relative concentration values.

Examples

out <- simulate_rel_change(10000, c(2, 5), c(0.5, 0.5), 0.7, c(0.1, 1))
hist(out, 20, probability = TRUE, 
     main = '', xlab = 'Fractional change in concentration')
