[R] crashing R through lattice

[Jon Loehrke]

I have been crashing R while using lattice.  My system consists of a Mac
Intel, R 2.5.1, lattice 0.15-5, and I plot through the default quartz.

R crashes after plotting several lattice functions.  Has anyone else
encountered this problem and does anyone know the cause, or a solution?

Is this a lattice:mac, lattice:quartz, Lattice:me issue?

example...

This crashes my system after plotting.

library(lattice)
haul<-as.integer(c(rep(1:12, 4)))
species<-c(rep("species 1", 12),rep("species 2", 12),rep("species 3",
12),rep("species 4", 12))
count<-c(895,540,1020,470,428,620,   760,   537,   845,  1050,   387,  
497,  1520,  1610,  1900,  1350,   980,  1710,  1930,  1960,  1840,  2410,
 1520,  1685, 43300, 32800, 28800, 34600, 27800, 32800,28100, 18900,
31400, 39500, 29000, 22300, 11000,  8600,  8260,  9830,  7600,  9650, 
8900,  6060, 10200, 15500,  9250,  7900)


qqmath(~count|species,
               	distribution=qnorm,
                prepanel=prepanel.qqmathline,
                panel = function(x,...) {
                        panel.grid()
                        panel.qqmathline(x, ...)
                        panel.qqmath(x, ...)
                },
                aspect=1,
                layout=c(2,2),#  where c=# of columns, R=Number of rows
			main=list ("QQnorm plot for 
.", cex=0.8),
                sub = list("",cex=.8),
                xlab = "Unit Normal Quantile",
                ylab=list ("variable in x units", cex=.8))


Thanks,

Jon
