Book recommendations: Multilevel & longitudinal analysis
Hi, does anyone out there have a recommendation for multilevel / random
effects and longitudinal analysis?
My dream book would be something that's both accessible to a
non-statistician but rigorous (because I seem to be slowly turning into a
statistician) and ideally would use R.

Select exactly n elements of a vector
In discussing permutation tests, _Modern Applied Statistics With S Plus_ suggests this (IMHO) rather elegant approach to generating a distribution of t-tests:
d<- ...some data...
ttest <- function(x) mean(x)/sqrt(var(x)/length(x))
n<-1000
res<-numeric(n)
for(i in 1:n) res[i] <- ttest(x<-d*sign(runif(10)-0.5)
The problem is that the sign(runif) results in random permutation of

intervals on plot
Dear all R users
I have been trying to plot a group of intervals by using the bottom
code:
> breaks <- factor(cut(col3,breaks=360+5*(0:155)))
> par(tck=0,lty="solid")
> plot(breaks,ann=FALSE,axes=FALSE)
col3 is just a column of 1500 floating point data.
Unfortunately when i do the plot, the x-axis has some of the intervals
as labels dispite me having both 'ann'

Formatted Tables
I was wondering is there anything in R that allows better presentated
tables. I think in S-Plus there is something like a LaTeX command that
allows such things to be used and formatted in LaTeX.
This is probably a bit much but just something that could be output to
both the X11 or a postscript file
Thank you for any suggestions

Help Need with aov()
Hi there,
I'm using R1.0.1 Windows 98.
This file contains some inputs and an aov function code. Can someone
check it for me? Somehow I got completely different answer when typing
them in R and in Splus.
Splus gives me this:

Anonymous cvs access
With Tony Rossini's help we have established anonymous CVS access to a
read-only copy of the main R CVS tree at cvs.r-project.org. This
would be of interest primarily to those who want to track the
development version (and who have access to CVS, of course).
To use anonymous cvs you must log in to the server under the name

No subject
Does anyone know of any comprehensive literature (like a book, collection of
articles, etc.) that walk thorugh example of ARIMA modeling with the ts
package of R? Genarlly if you've just started to learn the R-language and
are all week long with ARIMA, what is a fast-pace source that you would
recommend (to a beginner) ?
Thank you,

Mathematical niceties
I'd like to make axis titles, chart titles, legends and the like
mathematically nice (e.g., have proper superscripts and subscripts,
variables in italics, and so on). Ideally, one could go into ``math mode"
a la LaTeX, and write something like
plot(blah, xlab="Methane in $\mbox{cm}^3$ / g", blah).
This is just an ideal, but it would be nice. Is some approximation of this

Hey everyone,
What am I doing wrong? I loaded the MASS package with library(MASS), and
now when I type library() I get

left.solve
I have sort of an emergency question for the list. One of my professors
for an S-Plus intensive class distributed a function to produce partial
regression plots. I need to run it under R, because I'm doing the
homework on my home computer with a modem; hence I don't have the speed
required to emulate X-Windows and run S Plus off one of the campus
servers. Bottom line: I'm using R.

plot.design()
Greetings-
I'm working through Pinheiro and Bates' _Mixed Effects Models in S and
S-Plus_ using R (1.3.1 for linux). On page 13 (okay, so I haven't got that
far :)) is:
plot.design( ergoStool)
which returns on my system:
> plot.design(ergoStool)
Error: couldn't find function "plot.design"
any ideas?
Thanks.

Cluster graphs
I posted this to the sci.math newsgroup but didn't get any responses so I
was hoping someone here could help.
I have a number of items with "distances" of differences between each other.
What I want to do is to plot each item on a two dimensional plot such that
the positions on the plot indicate the approximate distance between each
item.
What I want to look at, basically, is a map

Potentially Stupid Question Department:
I just tried to load a few packages in a row. First I loaded MASS, then

Brace highlighting in R for the PC?
Hey everyone,
Might it be possible for future versions of PC-R to highlight the opening
brace in a pair, a la emacs? Programs that do that are infinitely
friendlier than those that don't.
Thanks,

Large datasets under R
Hello,
I recall reading a thread months ago on this mailing list about handling
very datasets under R, but I can't seem to find it. This has become
particularly important recently, because I've been playing with a dataset
containing information about every fatal car accident in the U.S. since
1975; in total, the relevant files are about 120 megs. I'd like to load
all of these into R

Dear developers,
I wonder would you consider making a save to a graphics file format (as opposed

What prompts this is that we have just finished my wife's thesis using R

the efficiency of gernerating it, especially when all the
