[R-sig-Geo] Plot variogramm in multi figure environment

[Thomas Hoffmann]

Dear all,


I calculated  variogramms and tried to plot them in a multi-figure environment. However, only the last plot appears in a single plot: 

cd30.vario = variogram(c30~1, gw.cal)
cd30.v.fit = fit.variogram(cd30.vario, vgm(0.01,"Sph",800,0.1))

cc30.vario = variogram(toc30~1, gw.cal)
cc30.v.fit = fit.variogram(cc30.vario, vgm(0.1,"Sph",1000,0.6))


par(mfrow=c(2,2))
plot(cc30.vario,cc30.v.fit)
abline(h=0.1,v=800)
plot(cf30.vario,cf30.v.fit)

Does anbody no way, and how to solve the problem

Kind regards
Thomas
