[Bioc-sig-seq] Of Mice and Lattice: twenty chromosomes and 7 automatic colours.

[Ivan Gregoretti]

Hello everybody,

How do you get the lattice package to use more than its 7 standard colours?


Now in little more detail:

I use lattice for plotting, well, everything. Above all, I find it
particularly useful to plot simultaneously a property segregated by
chromosome. One such example of multi-panelled plot would be this

or in a single panel like this

In mouse there are 20 canonical chromosomes. Because lattice has been
set to default to 7 standard colours, each colour is shared by three
different chromosomes. People get confused by that. It seems that
people follow colours rather than legends.

How do I 'reset' lattice to, say, 20 colours?

One example would be highly appreciated. John Steinbeck is excused.

Thank you,

Ivan
