I think that you have somehow initialised .Random.seed to be a list. Try
removing it (i.e. 'rm(.Random.seed)') and load the packages again.

I think I have an answer: SPSS uses absolute deviations from the _mean_ in
Levene's test.
(See calculation in
http://www.uvm.edu/~dhowell/gradstat/psych340/Lectures/Anova/anova2.html)
R uses absolute deviations from the _median_ (R help).
So the difference.

Thanks for the reply but I think you are confusing monotonic and
strictly increasing/decreasing. I also just used the y-value of the

Yes. You can always debug functions to investigate what's going on, too.
See ?debug.

Since you're on Windows, try the 'snow' package... the other suggestions
are highly suggested and recommended as well

will still produce a non-monotonic spline if you use for example
x <- 1:8
y <- c(-
When I wrap those values in to a matrix will it be still independent ? ( non
zero correlation).
Can I do this for any multivariate distribution which has the univariate
form?
Thank you for the response.

Hi Dimitri,
Have you looked at the examples for scale_x_date -
http://had.co.nz/ggplot2/scale_date.html? They show you how to both
set the limits and control the labels.

Here's another way to have different behaviour only for interactive sessions:
if (interactive()) {
winMenuAdd(menuname, NULL, NULL) # etc.

I am interested in creating a function that will take x number of lm

I'm using the package geepack to fit GEE models.
Does anyone know of methods for add1 and drop1 for a 'geeglm' model object, or
perhaps a method
try this:
MRfit <- function (...) {
models <- list(...)
do.call(anova, models)
}
I hope it helps.
