[R] Graph window is not available any more

[Jean-Marie Jungblut]

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.

Jean-Marie Jungblut.
