Hi, Francesco. The help for the function is always a good place to
look for this kind of thing. You can see that there are only a set
number of arguments and no '...', so you will not be able to pass in
other arguments. You could look at the plotDensity() function in the
affy package as another alternative that does have '...', so you could
pass in parameters of interest.

Hi Francesco,
I haven't used these plots much, but I don't think there's a way to do
this within the plotDensities function. An easy solution, though, is
to
modify it. Just open the function in the text editor and modify the
internal matplot function, as well as the corresponding input
variables.
I tried that, and it seems to work Ok.
