[BioC] Limma: can't use plotPrintTipLoess() with split.screen()

[michael watson (IAH-C)]

Hi

I just wondered if anyone knew how to use the plotPrintTipLoess()
function in limma with the R function split.screen()?  When I try,
plotPrintTipLoess() uses the whole window, rather than just drawing in
the screen I have selected

Thanks
Mick
