polr (MASS) and lrm (Design) differences in tests of statistical signifcance
...ptotic Normality of the estimate of b, and for finite samples b/se
is not exactly distributed as a t. But I also had the impression that
the Wald value was an approximation as well.

...t in the same session, the colors change to the dark
background, and I suppose the same trouble is happening. Isn't
trellis.par.set() going to remain in place for all following trellis plots?
Here's the code I used to make these 2 graphs.
x11(height=6.5,width=6.5)
data2003<- subset(elaine1,POLCYEAR==2003)
plot(data2003$OLDCRASH,data2003$RENUCYC)
modall <- lm(RENUCYC~OLDCRASH,data=data2003)
abline(modall)
