obviously not. any other suggestion? of course, it would be even
better if someone who knew what he is doing were to add this
functionality on demand (e.g., optional parameters) to the standard lm
classes. just a thought...

Is it a good idea to call it lme, since there's a widely used lme()
Dear R readers:
I have written a short lme.R function, which adds normalized
coefficients and White heteroskedasticity-adjusted statistics to the
standard output. Otherwise, it behaves like lm. This is of course
trivial for experts, but for me and other amateur users perhaps
helpful.

Absolutely wonderful. Yes indeed, instead of having two variables being
listed as group by in a sql statement one can use a combination of cbind,
unique, duplicated and indexing to get the same data without having to go
through second programs.

According to pp 197-198 of MASS 4, the Hauck-Donner phenomenon refers
to cases when the Wald approximations and the likelihood ratio tests
have different p values because of the former underestimating the the

What I am looking for is a function that goes with section 2.8 of the
"Introduction to R" PDF that ships with R. It says that the R objects are
vectors, matrices, factors, lists, data frames and functions. Is there a
function that returns this level of information or is that taxonomy just

You got to supply the absolute path of your files and the seperating symbol

Hello,
Does any one know an R-function that performs kernel density estimation when
there are many variables ? My data has up to 50 variables and several thousand
data points.
Does any one know an alternative method to perform nonparametric density
estimation on high dimensional data ?
I am fitting models to the responses to a questionnaire that has
seven yes/no questions (Item). For each combination of Subject and
Item, the variable Response is coded as 0 or 1.
I want to include random effects for both Subject and Item. While I

Hi Duncan:
Thanks for your hints.

collection every time I examine
