[R] help pairs

[Filippo Monari]

Hi everybody,
I'm exploring likelihood function having several parameters and I'm 
trying to work with pairs but I have the following problem.
I need to colour my dots depending on the value of the likelihood of 
just two parameters, thus basically I need different colour scale for 
each plot of the matrix.
I have been able to create the correct colour scale but I have not been 
able to change colors depending on the plot of the matrix.
Could anyone give any advice?
Regards,
Filippo
