[R] postcript file / xyplot function [Broadcast]

[Wiener, Matthew]

This is FAQ 7.22.  Lattice functions produce graphic objects, which are not
displayed by default. If you print your graph, you should be fine.  Also,
take a look at the documentation for panel.xyplot.  Using type = c("p", "r")
should make things simpler.

Subject: [R] postcript file / xyplot function [Broadcast]

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
