[R] "biplot" graphical options?

[Manca Marco (PATH)]

Dear R-help fellows

good afternoon.

I am struggling in the attempt to impose some graphical conditions (changing point symbols, colors, etc) to biplot function (I am using it to visualize the results of princomp) but I can't apparently manage to change anything but the axis... and I have been browsing manuals and vignettes without finding any explicit suggestions on how to operate...

Can anyone, please, point my attention to the relevant documentation?

Thank you in advance and best regards,
Marco
