EPS->LaTeX problem
Greetings-
I have a strange problem displaying a graph from R (1.3.1, linux) in a
LaTeX document of documentclass seminar.
I'm using graphicx to include the file:
\usepackage{graphicx}
...
\resizebox{\textwidth}{\textheight}{\includegraphics{crime.eps}}
When I do this, the entire slide (including the page number) is rotated
180 degrees. Any ideas why this happens?

Advice on using barplot
Greetings-
I'm venturing into a new (for me) area of using R: some presentation
graphics based on R data.
I'd like to compare two distributions of ordinal variables in relatively
small (N=203 and 207) subsets of an R dataset. I can get a reasonably
good picture of the distributions' differences with:
x11()

DBM databases for R?
Hello!
Can I use DBM databases (as they are used in Perl) for the import of
large datasets in R?
Thanks in advance for your help,

Plotting multiple columns on same graph
I'd like to produce a series of simple line graphs for my methods class
that show the three questions used on a repeated survey to make up a
particular index. The data frame is:

Memory error
Greetings-
Running R 2.4.0 under Debian Linux, I am getting a memory error trying to
read a very large file:
> library(foreign)
> oldgrades.df <- read.spss('Individual grades with AI (Nov 7 2006).sav',to.data.frame=TRUE)
Error: cannot allocate vector of size 10826 Kb
This file is, granted, quite large:

HLM-like analysis in R
Greetings-
I have some data on which I need to do something like a Hierarchical
Linear Model (please bear with me, I'm only learning the technique so I
don't know yet if my language is correct). Essentially I'm analyzing data
at two levels simultaneously; data are about individuals an organizations
of which they are members.
Can someone point me toward an appropriate package in R?

Does the perl language have an equivalent to browser?
I'm asking on this list because the question will be more easily
understood than on a Perl list. Lots of talented people using R also
know how to use Perl, so it's easier to ask them.
Running a Perl script with the -d switch can do some pretty neat
things, but as far as I can tell, every line has to be done
individually. Is there a way to specify where to stop in the way
browser() does

Measures of agreement
Greetings.
I've been experimenting with some algorithms for document classification
(specifically, a Naive Bayes classifier and a kNN classifier) and I would
now like to calculate some inter-rater reliability scores. I have the data
in a PostgreSQL database, such that for each document, each measure (there
are 9) has three variables: ap_(measure), nb_(measure), and
knn_(measure). ap is me

Sampling from a database
I use RODBC and RpgSQL quite a lot to access files stored in another
machine under PostgreSQL. Since I am now using files which do not fit
into R's memory, I would like to take random samples. What I would
like is to issue a query such as
SELECT * FROM file WHERE runif > 0.9
with "runif" being a uniformly distributed random number, generated on
the fly; but I cannot

Can't load e1071
After upgrading to 1.7.0 under debian linux, I can't get e1071 working
properly.
The first problem I had was that g++-3.0 was the standard compiler but
wasn't installed, so I installed it. e1071 then installed correctly, but I
get the following:

stacking vectors of unequal length
R-users --
I would like to make a single vector out of something like the following:
y0 <- rep(0,100)
y1 <- rep(1,20)
and stack them one on top of the other to a vector y with length 120.
Thanks,
Dan

calculating std err (SEM)?
Is there a "canned" function in R for finding the standard error of the
mean? I have tried
> sem <- function(x) c(mean =mean(x),
+ SEM = stdev(x)/sqrt(length(x)))
> sem(pnet.lai)
Error in sem(pnet.lai) : couldn't find function "stdev"
It looks like there is no stdev function in R
Thanks,

Extracting elements from an reStruct
Sorry if this is obvious, but my S skills aren't great and I haven't been
able to find it documented anywhere.
I want to write a new function for use with lme objects; the function will
simply calculate an ICC (aka "rho") for each level of a mixed-effects
model. What I need for this is pretty simple:
(c(var1..varn, residual)) / sum(c(var1..varn, residual))
where var1..varn

Validating R after it has been installed!
Hello All,
Just wondering if anyone may have a quick fix to our dilemma here.
I work for a company called HGS (Human Genome Sciences), we are in the
pharmaceutical business. Everything we do has to be tested and re-tested
to ensure we are providing the most accurate form of data. On top of that
everything is validated and regulated by FDA. What this means is every
application on a validated

Managing Data [Summary]
A while ago I asked about data management approaches in R. I was asked by
several people to post a summary of the responses and alas I am just getting
around to doing it. I received several comments, both on and off list.
Below is a compilation of these responses. Hope this is as helpful to
others as it was to me.
Best,

Dual Core vs Quad Core
Dear R-users,
I use R to run spatial stuff and it takes up a lot of ram. Runs can take hours or days. I am thinking of getting a new desktop. Can R take advantage of the dual-core system?
I have a dual-core computer at work. But it seems that right now R is using only one processor.
The new computers feature quad core with 3GB of RAM. Can R take advantage of the 4 chips? Or am I better off

plot() help
Please forgive my ignorance on grapics. I'm trying to make a relatively
simple plot with two line plots, same axes, by mean over a series of
dates. I can make the plot well like this:
plot(sort(tapply(first.anti.auth.sum,date,mean), partial=1), type="l",
col="yellow",ylim=c(0,2.0))
par(new=TRUE)
plot(sort(tapply(first.pro.auth.sum,date,mean), partial=1),
