[Tikzdevice-bugs] pgfSweave book project

[SyTpp]

> 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!
