histoPlot {fcros}

Histogram plot function of the fcros package results

Description

This function allows to have a histogram plot. It uses the statistics "ri" or "u1" obtained using one of the following functions: fcros(), fcros2(), fcrosMod(), pfco() or pfcoMod().

Usage

histoPlot(af, nbins = 50)

Arguments

af

This is an object obtained using the function fcros(), fcros2(), fcrosMod(), pfco() or pfcoMod()

nbins

This parameter is used for the number of bins in the histogram. Default setting is 50: nbins = 50

Value

Examples

   data(fdata);
   rownames(fdata) <- fdata[,1];

   cont <- c("cont01", "cont07", "cont03", "cont04", "cont08");
   test <- c("test01", "test02", "test08", "test09", "test05");
   log2.opt <- 0;

   # perform fcros() and pfco()
   af <- fcros(fdata, cont, test, log2.opt);
   af2 <- pfco(fdata, cont, test, log2.opt);

   # Histogram plots
   op <- par(mfrow = c(1,2))
      histoPlot(af);
      histoPlot(af2);
   par(op);
