pgfSweave book project

[SyTpp]

Dear list,

I'm about to start writing my PhD Thesis and I'd like to do it with
pgfSwaeve. Because it's gone be pretty big I'd like to use a book style
format and use multiple folders to structure chapters.
I have experience with multi-chapter/multi-folder projects in LaTex (with
the '\include' command) but I don't know how to active the same with
pgfSweave. So far I've only used pgfSweave for single .Rnw documents, like
reports or articles. Could you please hint we to a help page a describe
briefly how the structure of main .Rnw document and '\included' documents
should look like?

Kind Regards
Sylvia

Hi Sylvia-

As it turns out there is a command \SweaveInput{} that can be used in place of the \input command in your document. This will bring in and process your chapters as if they were part of the main document. 

A word of caution. If I remember correctly you have to be careful with your relative paths. For example if you have your main document "main.Rnw" and you have a chapter "chapter1.Rnw" in a directory "chapter1/" then you would have to put \SweaveInput{chapter1/chapter1.Rnw} in your main document. THEN say you have a figure "a.pdf" in a figures folder for chapter 1 say "chapter1/figures/" to include a figure from that directory in "chapter1.Rnw", you would have to list the path relative to the main document, "chapter1/figures/a.pdf" NOT relative to the chapter. 

Cheers,
-Cameron

> Dear Cameron,

thank you very much for your help! I set up a little example now with
thesis.Rnw and a chapter1/chap1.Rnw.
The figures folder is directly in the main directory, so not in every
single chapter folder. I specify only in the main thesis.Rnw the location
of the
figures and in the chap1.Rnw I do not have any document specifications but
only directly latex and pgfSweave code chunks.
Im principle I do get a thesis.pdf in the end that contains all the
elements I expect, however I have some errors on the way:

>> R CMD pgfSweave thesis.Rnw
c("‘chap1.Rnw’", "‘thesis.Rnw’") has unknown encoding: assuming Latin-1

>> make -f thesis.makefile
pdflatex -halt-on-error -interaction=batchmode -jobname "figures/fig-plot1"
"\def\tikzexternalrealjob{thesis}\input{thesis}"
This is pdfTeX, Version 3.1415926-2.3-1.40.12 (TeX Live 2011)
restricted \write18 enabled.
entering extended mode
All images exist now. Use make -B to re-generate them.

>> pdflatex thesis.tex

I don't know if I should just ignore the errors since I seem to get what I
want in the end, however I'm afraid as my project will now
grow bigger and more complicated (more figures, references,
bibliography...) I will run into problems later on. So, I'd prefer to have a
clean compilation to begin with, so in case things get more complicated I
know where the errors come from.

Can you help me with this?

Thank you and kind regards!
Sylvia

Hi Sylvia,

It doesn't look like you are getting any actual errors. The second
message is not an error, just a print out of what pgfSweave is doing.
The first message can be fixed by declaring the encoding of your
document, most likely it would be

\usepackage[utf8]{inputenc}

otherwise replace utf8 with the encoding you are using.
