[R] margins and device: different results with pdf() and svg()

[Agustin Lobo]

The following works fine with either the plot window or a pdf device:

pdf("test.pdf",width=12,height=8)
par(mar=c(5,4,4,5))
plot(421:450,1:30,xlim=c(300,1100), ylim=c(0,100),
type="l",col="blue",xlab="Wavelength",ylab="Transmittance %")
lines(401:1000, (401:1000)/10,col="green")
par(new=TRUE)
axis(4)
mtext("Reflectance",side=4,line=3)
title("Filters MCA01")
dev.off()

but if I use svg() I get a wrong plot.

Why? Any way to get the same plot in svg as in pdf?

Thanks
Agus
