Examples

# set parameters settings
fparams <- data.frame(m1 = 7, m2 = 7, shape2 = 4, lb = 4, ub = 14, pde = 0.02, sym = 0.5);
dparams <- data.frame(lambda1 = 0.13, lambda2 = 2, muminde = 1, sdde = 0.5);
sdn <- 0.4; rseed <- 50;

# generate synthetic data without using real microarray data as seed
mydata <- madsim(mdata=NULL, n=10000, ratio=0, fparams, dparams, sdn, rseed);

# calculate MMplot variables using samples 1 and 12
A <- 0.5*(mydata$xdata[,12] + mydata$xdata[,1]);
M <- mydata$xdata[,12] - mydata$xdata[,1];

# draw MA plot using samples 1 and 12
plot(A,M)
