plot() and Jpeg() increase font size and resolution

Thanks to Edzer and Roger, I can now plot with increased font sizes. However, jpeg still does not reproduce these, nor does it show up in high quality. What I would like to do is produce some highresolution jpegs.
Please specify the commands that you used, preferrably such that we can reproduce them, and specify which worked and which didn't the way you expected. Also please give the output of sessionInfo(), and tell us the platform you work on. Have you tried producing png, did that work? -- Edzer

Dear list,
I am having troubles increasing the fontize when plotting a
variogram{gstat} and its model (vgm) with plot and using jpeg(). Also
the resolution in the jpeg call does not work. I am using R2.4 on
Mandriva 10.2 linux.
I can change fontsize with cex.axis in a normal plot, so I presume it
has to do with plotting the variogram model. Any help on how to
increase the font size and resolution would be appreciated?
R-calls:
v1<-variogram(log(z)~x+y, loc=coordinates(shp1),data=shp1)
m1<-vgm(0.0175, "Gau", 200000,0.052)
jpeg(file="LOTPLAN_variogram_mod.jpg", bg="white", res=300,
pointsize=16, width=1200, height=1200, quality=100)
plot(v1,plot.number=F, model=m1, ylim=c(0.04,0.08), col="black",
cex.axis=1.5)
dev.off()
Thanks Herry
