Sweave: looping over mixed R/LaTeX code
Dear guRus,
I would like to loop over a medium amount of Sweave code, including both R and LaTeX chunks. Is there any way to do so? As an illustration, can I create a .tex file like this using a loop within a .Rnw file, where the "1,2,3" comes from some iteration variable in R?

ggplot2: deterministic position_jitter & geom_line with position_jitter
Dear guRus,
I am starting to work with the ggplot2 package and have two very dumb
questions:
1) deterministic position_jitter - the jittering is stochastic; is there
any way to get a deterministic jittering? For instance:
example.data <-
data.frame(group=c("foo","bar","foo","bar","foo","bar"),x=c(1,1,2,2,3,3),y=c(1,1,0,2,1,1))

simple graph question: manipulating variable names
This is a simple problem that has stumped me: I'm trying to loop through a
few dozen variable names in graphs. I've tried various approaches like
this:

ivs <- c("oneiv", "anotheriv", "yetanotheriv")
dvs <- c("onedv", "anotherdv", "yetanotherdv")
for (iv in ivs) {
for (dv in dvs) {

Sweave output encoding in R-2.10.0beta on Windows (Rgui <-> Rterm)
Dear developers,
I have come across a (somewhat strange) change in the encoding of Sweave
output from R-2.9.2pat to R-2.10.0beta (apparently specific to Rgui) on
Windows installations. Of course, the NEWS file contains quite a few
changes concerning encoding, but I was not able to locate an entry which
explains the observed behaviour. I am not very familiar with

Methods not loaded in R-Devel vs 2.8.1

In version 2.8.1 these two are reported whereas in R-Devel (2009-01-28 r47766). What have I missed? What has changed and how can I rectify the issue? Your help and pointers are welcome.

Antwort: Re: Crash with Unicode and sub (PR#14114)
I don't know about the technicalities, but Peter Dalgaard said the
offending code also causes R to come to a stop using SUSE + WINE. Is it
possible to run that lot on top of valgrind? Of course, it will probably
take all day ...
If not, I have a clue which might help. The problem seems to lie in the
"sub" routine. In the original report I used

Help writing a Scheffe Contrast function for R
Hello,
As a new user of R (less than a month) I have got my hands on several books and am pouting through the net looking for help in gaining understanding of this powerful tool. I am becoming more proficient with using basic functions to conduct basic statistics. I am now looking to learn how to write code. After a few small worthless functions I decided to try to create a function that was

all.names() and all.vars(): sorting order of functions' return vector
Dear list-subscriber,
in the process of writing a general code snippet to extract coefficients
in an expression (in the example below: 0.5 and -0.7), I stumbled over
the following peculiar (at least peculiar to me:-) ) sorting behaviour
of the function all.names():
> expr1 <- expression(x3 = 0.5 * x1 - 0.7 * x2)
> all.names(expr1)

Poisson GLM with a logged dependent variable...just asking for trouble?
Dear R-helpers,
I'm using a GLM with poisson errors to model integer count data as a
function of one non-integer covariate.
The model formula is: log(DV) ~ glm(log(IV,10),family=poisson).
I'm getting a warning because the logged DV is no longer an integer.
I have three questions:
1) Can I ignore the warning, or is logging the DV (resulting in
non-integers) a serious violation of the

R CMD Sweave versus Sweave() on Windows
Dear list subscriber,
I am quite puzzled by the behaviour of processing Sweave files within an R session, i.e.

In the former the environmental variable 'SWEAVE_STYLEPATH_DEFAULT = TRUE' is obeyed (this is set in etc/Renviron.site as well as under the users home directory in .Renviron). That is the hard-coded path to Sweave.sty is
