Specifying search position for attached package
...the search path (as with the pos argument to attach())? From the
documentation for library(), this doesn't seem like an option.
(I know I can detach packages and then reload them in the order I want;
I'm looking for a less clumsy way.)
Thanks,
Jim

Lexical scoping question
...# 5
Checking the environments of these functions, I see that "y" is indeed
bound to the value 2 in both cases:
es <- lapply(fs, environment)
ys <- lapply(es, function(env) get("y", env)) # list(2, 2)
?
Thanks for help,

T-Distribution
Dear sir,
I would ask if there are in R some code to generate a random sample
from a mvariate student distribution like that one wich generate the
multivariate normal one i mean( rmvnorm(n, mu, sigma)
Second question : if R can plot density 3Dcurve I don't mean de
histogram but de hole density function(normal for example).
I use a windows version of The R software
Thank you in advance

summarizing dataframe
Hi Listers,
Surely, I just have a mental block and there is a more elegant way of
creating a summary count (other than extracing it from ftable). I''d like to
create a new data.frame containing counts of spell by loc ie have three
columns showing spell,loc,count. Below the data.frame...
Any help appreciated
Thanks Herry

Multiple random effects inlme?
Moi!
I was helping to teach a course on mixed models this week, and we came
across a problem with coding more than one random effect in lme when
they aren't nested.
As an example, suppose we have an experiment where we sample moths from
several populations, and place the moths on different trees, and measure
a trait (in this case survival of offspring, but that's less
important). We

generate a series of fucntion
Hi there,
I want to generate a large amount of functions,
say f=function(x,t) exp(-t[1]-t[2]*g_1(x)-t[3]*g_2(1+x))
where g_1(x) and g_2(x) are from a long list of moments, such as x, x^2,
log(x), log(1+x) .. and so on.
Any suggestions on how to do this efficiently?
thanks a lot.

inverse prediction and Poisson regression
Hello to all, I'm a biologist trying to tackle a "fish" (Poisson Regression) which is just too big for my modest understanding of stats!!!
Here goes...
I want to find good literature or proper mathematical procedure to calculate a confidence interval for an inverse prediction of a Poisson regression using R.
I'm currently trying to analyse a "dose-response"

R tools for large files
I'm wondering if anyone has written some functions or code for handling
very large files in R. I am working with a data file that is 41
variables times who knows how many observations making up 27MB altogether.
The sort of thing that I am thinking of having R do is
- count the number of lines in a file
- form a data frame by selecting all cases whose line numbers are in a
supplied vector

data.frame as argument to data.frame
Hello,
Documentation for data.frame says,
"If a list or data frame or matrix is passed to data.frame it is as if
each column had been passed as a separate argument, with the exception
of matrices of class model.matrix. ".
This is not quite true:
> data.frame(a = 1:2, b = 1:4, c = 1:8) # replicates vectors as
necessary

Write XML according to ggobi DTD
Hi,
Has anyone out there written a function to take a data.frame as input
and generate XML that conforms to the DTD for ggobi ("ggobi.dtd")? In
other words, like a simple version of the writeSDML function in the
StatDataML package, but using ggobi.dtd instead of StatDataML.dtd.
It looks easy to write such a function to handle data.frames with only
numeric data, but a bit of work with

gnuclient.exe as pager ?
Hi,
I see there are some previous threads on gnuclient.exe, but I can't
figure this out based on those...
I recently started using ESS with Xemacs. I'm on Windows XP. On starting
iESS, my editor gets set to 'gnuclient.exe'. I don't understand how this
works, since there is no executable anywhere on my machine called
"gnuclient.exe". But I have no complaints: I like
