Hi, I would like save a curve in a postscript file. It when I use a common "plot" function (plot) postscript(file="file.eps") plot(x,y) dev.off() It's not working with the "xyplot" function (lattice package). postscript(file="Z",height=8,width=8,horizontal=FALSE) xyplot(data[,3]~data[,2]|data[,1],panel=function(x,y){panel.xyplot(x,y) COEFF<-coef(lm(log(y)~x)) panel.curve(exp(COEFF[1]+COEFF[2]*x)) dev.off() Do anyone know how to use the postscript function with a xyplot function ? Thanks by advance Jessica Gervais [[alternative HTML version deleted]]
