I finally made it to the 24chr DNAcopy multiplot but as my chromosomes are already named chr1 ... I get plot titles like 'Chromosome chr1' which is not nice and too long to see the actual chr number. Ideally, I would like to not print 'Chromosome'

Is it possible to substitute the plot titles with a vector of names.

my current command is:

  # one plot per chromosome in mosaic

  plot(segment, plot.type="s")

I tried 'main' and 'title' which have no effect.  Can I also remove index below each plot, I tried xlab without success here too.

Thanks

If we examine the source code of plot.DNAcopy then it appears the 'main' argument is hard-wired in.  My only suggestion is to copy the source into your own function, and modify the behaviour to give you want you want - I don't know of a way to capture the make-up of a base plot in a way that it can be programmatically altered after it has been generated.
