[BioC] Multiple plots

[kfbargad at lg.ehu.es]

Hi all!

I don´t know where, but I remember having seen an image of several MvA 
plots of a number of chips on the same picture.

I know that to plot an MvA plot of one chip with a fitted line I 
should do something like 

> plot(ma, slide=1,main="MvA plot")
> lowessCurve(ma)

But what should I write if I want to get MvA plots of my 10 slides on 
the same figure?

I have looked for an answer on the web, but can´t find anything. Any 
help would be much appreciated.

Regards

David
