[R] Jpeg and pixel

[thomas.schwander at mvv.de]

Hi Brian,

Thank you for your fast answer. It looks a little bit better now. Nevertheless I see pixels. May it depend on the font used?
In the praeambel I use 
	windowsFonts(Frutiger = windowsFont("Frutiger 45 Light")) 
	par(family="Frutiger")

And later, to create a wide table on the right of the plot
	text(par("usr")[2] + 3.95, ... ,family="Frutiger") 

Regards,
Thomas

png(), as the help page suggested.  The 'P' in JPEG stands for 'Photographic', and the format is not intended for text and line diagrams.
