Re: [R] odfWeave repeats output

I'm still testing it out, and have used both of these code chunks, which I copied off a blog: ... The really weird thing is that I have replicated the problem across two operating systems (dual boot on the same computer), windows 7 64bit and Linux Mint 11 (which is Ubuntu, not sure which version I'm afraid). I've been unable to find anyone on any forums or anything with the same problem. Using R v2.13 on Windows, v 2.12 on Linux, was using RStudio but just tested it without (just in case) and it does the same thing. Any suggestions gratefully received. You might try downgrading to an earlier version of the XML package (e.g. version 3.2.0).

Re: [R] eps file

I need to create eps file which is the required figure format

create files in pdf or wmf format but not in eps format. Is
there a way to convert pdf or wmf to eps? or alternatively, how
can I create an eps file in R?
see ?postscript
The postscript produced by R is EPS (_Encapsulated PostScript_)
compatible, and can be included into other documents, e.g., into
LaTeX, using '\includegraphics{filename}'. For use in this way you
will probably want to use setEPS() to set the defaults as
horizontal = FALSE, onefile = FALSE, paper = special.
dev.copy2eps: for copying from screen to EPS.
Xpdf (http://www.foolabs.com/xpdf/) includes a pdftops utility for
converting PDF files to (Encapsulated) PostScript.
