...n my graph but it doesn't work with xyplot(). With the plot function, abline() is ok but with plot it doesn't make what I want. Maybe it's a little thing to change in plot() but I don't find what! With xyplot I write this : Xyplot(m~ordered(l,levels=1), type="b",xlab="lagdist",ylab="Moran'I",lty=1,lwd=2,cex=1.5,pch=pch) Abline(h=0,lty=2) There's no error message but no line too. If someone see my error or know how to do, thanks in advance. Chloé Archinard CEFE-CNRS 1919 Route de Mende 34293 Montpellier, Cedex 5, France -- passerelle antivirus...
