eps file not positioned properly in latex document
Dear People,
I am trying to include a barplot (see code below), in a latex document.
However, the plot appears in totally the wrong position. I know this is
not an R question as such, but the eps file is produced by R and I thought
that perhaps other people had had similar problems and could give me
pointers. Am I doing anything obviously wrong?
Sincerely, Faheem Mitha.
PS.

rsync logging and permission problems
Dear rsync people,
I have just started using rsync for backups. I have had a couple of
issues. Note I'm trying to use rsync as user using ssh between two
machines both running Debian GNU/Linux potato (2.2r3). The local machine
is currently running 2.4.6-1 and the remote 2.3.2-1.2.

than I can read it. I was wondering if

loading compiled C++ code as shared library
Dear People,
Over the last few days I've been writing C++ to compile as a shared
library (previously I have always used C). Not entirely to my surprise, I
am getting errors. Specifically, when I try to load the shared library, I
get
Error in dyn.load(x, as.logical(local), as.logical(now)) :

barplots with pictex
Dear R People,
I want to include a barplot corresponding to a simple discrete probability
distribution in a LaTeX document. I decided to use the pictex
driver. After a certain amount of messing about, I came up the stuff
below. It does not look too bad, however, there is one very obvious piece
of weirdness, ie. the y axis terminates at 0.1 and does not extend down
further. I tried to adjust this

passing arguments to R CMD SHLIB
Dear People,
I want to run gcc with optimisation turned on (-O2), and with -Wall (all
warnings) enabled, when using R CMD SHLIB. When I do make, which is

in this case, I get

testing for integer

Consider the following fragment of R code

{
.C("choose",as.double(n),as.double(r),comb = double(1))$comb

concatenating lists
Dear People,
I have been trying to perform concatenation operations on lists without
success. Consider the following example.
> x <- runif(2)

> xy <- list(x,y)
> xyz <- list(x,y,z)
I want to have a function foo such that foo(xy,z) is the same as xyz. This
appears not to be as easy as I thought, though there must be a way.

R question
I have the following question, which is elementary but I am unable to
answer.
In a for(i=10) loop, I am trying to represent the 10 1-dimensional vectors
l1, l2,... l10 by some expression that will run through these values.
ie. soppose I want to add l1 + ... + l10
I could go
x <- 0
for(i in 1:10){ x <- x+ l(i)}
This should return x to be the sum of the 10 li's for i from 1 to 10

R CMD SHLIB uses foo.c instead of foo.cc if both are present (PR#2644)
Full_Name: Faheem Mitha
Version: 1.6.2
OS: Debian GNU/Linux
Submission from: (NULL) (209.42.199.193)
Suppose you are making a shared library using
R CMD SHLIB foo.cc
If there is a file called foo.c in the same directory, then it will be used
instead.

choosing g/g++ compiler executable in R CMD SHLIB
Dear People,
After considerable effort, I managed to install gcc-3.0 on my Debian
system. However, Debian keeps gcc-2.95 around as the default compiler, and
gcc, g++ point to the 2.95 version. The 3.0 versions need to be explicitly
invoked as gcc-3.0, g++-3.0 etc. How can I get R CMD SHLIB to invoke
gcc-3.0 instead of gcc and g++-3.0 instead of g++? I would like this to be
done by default but

Dear people,
I compiled a bit of C code into a shared library cftpR.so, and load it

clustering methods in R
Dear R people,
I need to do some work with clustering, but know next to nothing about it
at present. R has (at least) three clustering packages, cluster, mclust,
cclust.
I was wondering if someone can direct me to some good books where I could
find documentation and background on the functions in these packages. The
html help in these packages lists the following as references. Can people

linear models
Dear R users,
I have a couple of linear model related questions.
1) How do I produce a fixed effect linear model using lme? I saw somewhere
(this may be Splus documentation since I use Splus and R interchangeably)
that using lme(...,random= ~ -1 | groups,...) works, but it gives the same
as lme(...,random= ~ 1 | groups,...), ie. fits a random effect intercept
term.
The reason why I want to do

removing NA values from data frame & identification function
Dear people,
1) I have a data frame with named columns.For concreteness, let us say
that I created a data frame from the vectors fee, fi fo, fum by
giant.df <- cbind(fee, fi, fo, fum)
Now, some of the entries in fee, fi fo fum are NAs. I want to remove any
row which contains a NA, thus creating a new, smaller data frame, with the
same column names. This seems like something people would need
