Hi all, I have currently been using the book Modern Applied Statistics with S from Venables and Ripley. At chapter 6 on Linear Statistical models I wanted to produce the plot as shown by "Figure 6.1" using Whiteside's data. xyplot command seems not to work on my version of "R"(version 1.7.0) running on different environments (Win XP, Win 98 and Win 2000). I then used the scripts for "R" provided with the package MASS pasting the following lines into the R console:
library(MASS) library(lattice) options(echo = T,width=65, digits=5, height=9999) trellis.device(postscript, file="ch06.ps", width=8, height=6, pointsize=9) options(contrasts = c("contr.helmert", "contr.poly")) xyplot(Gas ~ Temp | Insul, whiteside, panel = function(x, y, ...) { panel.xyplot(x, y, ...) panel.lmline(x, y, ...) }, xlab = "Average external temperature (deg. C)", ylab = "Gas consumption (1000 cubic feet)", aspect = "xy", strip = function(...) strip.default(..., style = 1)) After this no graph shows up, no error message is displayed and other siple commands like hist(x) or plot(y,x) do not produce any graphs. The Graph window seems to be disabled until I close the session without saving the workspace image. Thank you very much for any reply or comments.
