I can't reproduce that with ggplot 0.4-0 as some of the functions you are
using do not appear to be part of ggplot (I suspect you are using a newer
version of ggplot than you have released) but the following illustrates
the difference using "R version 2.5.0 Patched (2007-05-01 r41405)"
and lattice 0.15-5 and grid 2.5-0 on Windows XP:
library(lattice)
xyplot(conc ~ uptake, CO2, xlim = Inf)
traceback()
print(xyplot(conc ~ uptake, CO2, xlim = Inf))
traceback()
