But first, stop using attach(), it creates confusion and is probably the
reason why you did not think of passing your data.frame object to
svydesign().

You were advised to use svyglm(), not glm(). It's usually considered

Well, I gave you one idea, but for us to tell you more you need to give
us the code you are using. A better solution would be to spend some
money to buy more RAM, given it's quite cheap these days, and to install
a 64-bit version of Linux and R, if your computer supports

Hi everyone!
In a package I'm developing, I have created a custom function to get
jackknife standard errors for the parameters of a gnm model (which is
essentially the same as a glm model for this issue). I'd like to add
support for bootstrap using package boot, but I couldn't find how to
proceed.

Hi!
I just discovered that cutree() and cut.dendrogram() do not assign the
same cluster numberings when called on the same tree. More specifically,
cutree() assigns cluster numbers by order of appearance in the data,
while cut.dendrogram() sorts clusters by height (see example below). I

I'm using R2HTML in my RcmdrPlugin.temis package to output localized
strings to a HTML file. Thus, I insert a simple header at the top of the
file to specify what encoding is used; if I don't do that, Web browsers
assume it is latin1, which is not always true.
