[Tikzdevice-bugs] TikzDevice and non-pdf output

[Lorenzo Isella]

Dear All,
I normally produce my plots with ggplot2+tikzDevice and I am pretty 
happy with this. My output is usually a pdf, however, there are journal 
asking you to submit the artwork as a tiff or an eps file.
How can they be produced with tikzDevice? In particular, I refer to eps 
files.
My goal is to produce them on the fly, rather than convert a pdf into 
another format (the cure may be worse than the disease...).
Any suggestion is appreciated and I can produce a small example (leading 
to a pdf) if needed for the discussion.
Best Regards

Lorenzo
