If you are on unix/linux/mac/cygwin, you could do that in a shell script and

David,
Faraway suggests using the Hosmer Lemeshow test in the case of a
binary response, and discusses the inadequacy of Wald statistics.
However, I'm not sure it applies here due to the limited number of
cases.
Thanks, Ehud.

Surely Faraway does not suggest using the Wald statistic in preference
to the deviance?
Even if the distribution of deviance is not exactly chi-square, it
appears generally accepted that a comparison of the difference in
deviance to the chi-square statistic is better than using the ratio of

If you were doing that with the full sized do1 and dr1, then my guess

don't have an answer, since there were no missing values in those

I should have been more explicit. Run ?lm . You'll see this:
"lm(formula, data, subset, weights, na.action,
method = "qr", model = TRUE, x = FALSE, y = FALSE, qr = TRUE,
singular.ok = TRUE, contrasts = NULL, offset, ...)"
So, in addition to specifying the formula, you have to speci

Dear Andreas,
melt() and cast() are nice tools for this kind of problems. They both
reside in the reshape package that automatic loaded when ggplot2 is.
a <- rnorm(100)
b <- rnorm(100,1,2)
c <- rnorm(100,2,0.5)
ds <- data.frame(a = a, b = b, c = c)
library(ggplot2) # loads qqplot2
ggplot(melt(ds)

Are you trying to imply that people should be able to answer a
question that included no data? As others have pointed out, our powers
of telepathy are generally less than commonly assumed.
