Dear list,
Has anyone a suggestion for a package/tool that will generate microarray data (according to some desired/provided distribution) to be used in a simulation study?
Now i am using the code below, but i wondered whether something more appropriate is available.

Thanks,
Guido


set.seed(1)

x1 <- rnorm(1000, mean = 6.0, sd = 2.81)

x2 <- rnorm(1000, mean = 6.01, sd = 2.81)

x3 <- rnorm(1000, mean = 5.99, sd = 2.81)

grp1=cbind(x1,x2,x3)

#repeat for other group of n=3.
