Not to contradict Prof. Ripley re the merits and de-merits of the z ratios in
an ARMA setting -far from it-, I'd like to point out that in the package

myd1 - myd-2
plot(range(density(myd)$x, density(myd1)$x),
It needs to be done by hand, in that partialPlot() does not handle more than
one variable at a time. You need to modify its code to do that (and be ready
to wait even longer, as it can be slow).

As far as I understood, your problem comes from the density() function -
the domains of myd and myd1 are different, which causes slightly shifted x

But if I do, then I can go back to those for whom I am doing the analysis
and tell them that. Not before.
This sad truth being said - can I do it directly in the function, without
building a
Good day.
I create a data frame like this:
data - data.frame(a=1:10,b=11:20,c=21:30)
I can subset this data.frame by saying:
data[data$a7,]
and I get this result

Dear all,
a question about the package boot: is it possible to bootstrap a
function of arguments of different length? is there an alternative package?
below an example of a simple try,
many thanks

library(boot)
blue-c(4, 3, 4, 1, 2, 3, 1)
red-c(4, 3, 4, 1, 2, 3, 1, 2, 3, 1, 3, 2)
You can build the variance matrix you want manually with cov(x,
use=pairwise).
You can supply a variance matrix to princomp with princomp(covmat=outputOfCov).
See their manual pages for details.

Hello,
The second argument to your function must be a vector of indices, like
the manual page for ?boot says.
And you were missing a comma. That's what the error message was saying.
library(boot)
blue-c(4, 3, 4, 1, 2, 3, 1)
red-c(4, 3, 4, 1, 2, 3, 1, 2, 3, 1, 3, 2)
test1-function(x, d, y){
Yes, that's what I've done.
I was just wondering if the function can do it itself.
If not - no problem.

You should look at findInterval. Used with as.numeric it could do what you
request although it has a much wider range of uses.

Thank you so much!
After setting up GTK, rattle works!
I think the problem was caused because GTK had not been installed
automatically.
I guess it has something to do with the fact that my labtop is not private.
Thanks again.

Dear List
I am looking for the recommended way to create a formula inside a

is a difference
I didn't see where you said what your goal was in making the environment of
a formula and empty environment. I'm guessing that you want to make sure
the variables in the formula come from the data.frame given to a fitting
function
