expression_arraywide {biocDatasets}R Documentation

Generate expression for a whole array

Description

Generate expression values for a whole array

Usage

expression_arraywide(n,
                     noise_mean = 50, noise_sd = 5,
                     signal_mean = 500, signal_sd = 0.9,
                     highbump_percent = 5,
                     highbump_mean = 6000, highbump_sd = 500)

replicate_arraywide(x)

Arguments

n Number of probes
x A vector of expression values
noise_mean Mean for the noise
noise_sd Standard deviation for the noise
signal_mean Mean for the signal
signal_sd Standard deviation for the signal
highbump_percent Percentage of probes from the `high bump'
highbump_mean Mean
highbump_sd Standad deviation

Details

XXX

Value

A vector of numerical values (and of length n, or length(x)))

Examples

y <- expression_arraywide(1000)
y2 <- replicate_arraywide(y)

library(lattice)

densityplot(~ c(y, y2), groups = rep(c(1,2), rep(length(y), 2)))
