Examples

  ## draw the heatmap for a coverate matrix that was previously calculated 
  # using the cov.matrix function for a BAM file containing ChIP-seq data 
  # from a H3K36me3 histone modification experiment
  data(DF_H3K36me3)
  draw.heatmap(DF_H3K36me3,outfile="testHeatmap.png")
  
  ## Now, draw two heatmaps for 2 different coverage matrices previously 
  # obtained for the same H3K36me3 histone modification experiment and its
  # respective 'control' file
  data(DF_H3K36me3_control)
  
  # create a list with the two matrices
  input_l=list(DF_H3K36me3,DF_H3K36me3_control)
  draw.heatmap(input_l,outfile="testHeatmap.png")
