plot() and Jpeg() increase font size and resolution
plotting variograms in gstat is done through xyplot in lattice; you'll find where it gets it's defaults by library(lattice) trellis.par.get() ?trellis.par.set -- 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
