Sweave, cacheSweave, and data frame
Dear All,
I have been using Sweave (mainly via the Sweave.sh script) and really like
it. I am working a paper (using Sweave, of course) which includes several
time-consuming computations, and it gets tedious to re-compile the whoel
thing every time I made changes. Then I discover the "cacheSweave" package,
which seems the right solution to my problem. I only have on problem. Here

I want to use Sweave, but only sometimes
Does anybody have a workable system to run an Rnw document through
R-Sweave when necessary, but to just run it through LaTeX if no new R
calculations are needed? I.e., the figures already exist, I do not
need R to do more work for me, so I send the document straight to
LaTeX.
I want to leave open the option that I might need to run the document
through Sweave in the future, so I don't want

Sweave for "big" data analysis
Hi,
Maybe I'm missing the point here...but let's suppose you are working with
"large" data sets and using functions that take a significant amount of time
to run in R. I woulnd't like to run these functions every time I call
Sweave("myfile.Rnw") within R. What is the "common" practice to use Sweave
in these situations. I would just run the function once,

cacheSweave fails when used in conjunction with rjags
Hi all,
I use the excellent packages rjags and cacheSweave, and unfortunately
seem to have found an incompatibility between them. Below are a
minimal .Rnw file and corresponding JAGS model file which illustrate
the problem:
*** JAGS model file; name=j.bug ***
model {
mu ~ dnorm(0,1.0E-5)
sigma ~ dunif(0,100)
for(i in 1:length(y)) {
y[i] ~ dnorm(mu,sigma)
}
}

Sweave: Avoiding recompilation of figures
Hello everybody out there using Sweave,
There are some complicated SQL queries and laborous calculations against large data included as R code chunks using Sweave in my LaTeX document.
These code chunks create graphs that do not change most of the time, but they are of course recompiled every time I run Sweave on my file for update of minor changes to the LaTeX text.
Is there an option

cacheSweave / pgfSweave driver for package vignette
Dear list,
I wish to use a specific driver to process an sweave document in the
inst/doc directory of a package. Specifically, I would like to use
either cacheSweave or pgfSweave to speed up the creation of the
vignette which requires lengthy computations. The same request would
also apply to the highlight driver, to provide syntax highlighting of
R chunks.

Sweave-LaTEX question
Hi:
I am working on a publication and I have heard about LaTEX but I haven't actually tried to learn about it until today. I've found a few examples but I can't actually make them work properly. I have a couple of questions:
Does LATEX have to be installed on your computer? How does the xtable package and Sweave work together? How can I make the code below create a table as pdf file?

vignette compilation times
Dear All
I am preparing a number of vignettes that require a very long time to
process with Sweave. The longest one takes 10 hours. I love the weaver
package!
Is a package that includes such a computationally intensive vignette
acceptable on CRAN? Are there any guidelines here?

Sweave: option keep.source=TRUE and package cacheSweave
Dear all,
When I use the cacheSweave package together with the Sweave option
keep.source = TRUE, all the LaTeX code before the Sweave code chunk is
included in the TeX file to be compiled. For example, with the
following Sweave file
\documentclass[12pt]{article}
\usepackage[nogin]{Sweave}
% Sweave options
\SweaveOpts{keep.source=TRUE, strip.white=TRUE, eps=FALSE, pdf=TRUE}

Sweve/cacheSweave
Hi there
I have a problem with using Sweave in combination with the option driver = cacheSweave.
Whichever code I try to run - when it comes to converting the tex file into pdf it comes up with the same errors (\csname \endcsname errors). Does anybody have an idea what it going wrong?

Sweave : change value in rnw file to generate multiple "single" reports ?
Hello,
I'm still trying to make the life of my colleagues easier. Nice, isn't it ?
At the moment, I'm looking for a way to generate multiple "single report".
In fact I have a .rnw file which send a query to a MySQL database

packages with Sweave and knitr vignettes?
Now that R 3.0.0+ supports non-Sweave vignettes, R-exts \S 1.4.2 seems
to imply that
it is possible to include both Sweave and knitr vignettes in a single
package.
I'm wondering
if anyone has tried this and/or if there are some hidden gotchas putting
this into practice,
and concerned about creating problems with CRAN checks if I try this.
Consider two vignettes:

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.
Sweave("foo.Rnw") versus R CMD Sweave foo.Rnw
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

Sweave and uttf-8 under Windows XP
Hi list,
I need to process a Rnw file and and a csv file (both are encoded in
UTF-8) under Windows XP (R Version 2.11.0, i386, mingw32).
I can source and run the Rnw file:
> Stangle("Bericht.Rnw")
Writing to file Bericht.R
> source(file("Bericht.R", encoding="UTF-8"))
which runs fine, but running Sweave() failed:

Sweave and \input or \include LaTeX commands
Hello!
I was just wondering if Sweave can work with \input or \include
LaTeX commands. So, is it aware of such a possible hierarchy in
documents. I would test that, but I don't have such a report
available at the moment.
I thought of that when I was writting shell script for Sweave
from command line and I have solved that part there.

Sweave - if \Sexpr{} than \SweaveInput{"my.Rnw"}
Depending on an R computation I would like to include an Sweave documents
in the main Sweave document.
How can I do it?
So I was thinking .... to use Latex features :
\newif\ifpaper
\ifpaper
\SweaveInput{"my1.Rnw"}
\else
\SweaveInput{"my2.Rnw"}
\fi
But how do I set paper to true or false given an \Sexpr ??
\papertrue % or
\paperfalse
Any ideas?
cheers

Sweave, Texshop, and sync with included Rnw file
Hello everyone.
I am in the process of writing a book in Latex with Texshop, on Mac.
This book contains a lot of R code, hence the need to use Sweave.
I was able to compile Rnw files, and to sync back and forth from the pdf to the source Rnw.
My problem now is that the book is divided in Chapters, and every chapter is in its own Rnw file.
I can compile them from the main one (book.Rnw) using the

Sweave in makefile under Win XP
Hi all.
To automate the production of a document I want to have something like:
test.tex : test.Rnw
"Sweave("test.Rnw") "| R --no-restore --no-save
in a makefile.
This however gives an error as R states: Sweave("test.Rnw") : not found.
I use R-1.9.0pat (040424 I think) on Win XP.
Any suggestions, hints or plain help appreciated.

\include-mechanism in Sweave?
Dear HelpeRs,
I'm very fond of Sweave and I use it as often as possible. It'a a pity
I can't use it for larger projects or can I?
For instance suppose I have three files file1.rnw, file2.rnw and
file3.rnw with Sweave code. Working on file2.rnw I whould like to
exclude file1.rnw and file3.rnw temporarily and joining all of them
later. This amounts to a mechanism similar to using
