[R] odfWeave : problems with odfInsertPlot() and odfFigureCaption()

[Emmanuel Charpentier]

Dear Max, dear list,

I have trouble using odfInsertPlot to insert plots outside fig=TRUE
chunks.

My goal is to dump a bunch of (relatively uninteresting, but required)
graphs from within a loop, possibly interspeded with some tables. This
is not possible within a normal fig=TRUE chunk.

odfInsertPlot() is able to insert a previously saved plot. When used in
a fig=TRUE, results=hide chunk, it produces just a blank frame (with a
caption if caption=odfFigureCaption() is used).

Used in a fig=TRUE, results=xml chunk, it produces an error at file
rte-assembly (see end of post). However, when wrapped in a cat(), the
same code produces 1) the figure (without caption), then a blank frame
with the caption, or just the figure (without caption) if the caption=()
argument is absent.

The same cat(odfInsertPlot()) construct can be used in a results=xml
chunk (no fig=TRUE) ; however, I found no way to insert the caption.

Therefore : I can programmatically create graphs and insert them via
results=xml chunks, but I can't caption them.

Do someone has a workaround (except reprogramming odfFigureCaption()
with a new argument taking the output of odfInsertPlot()) ?

Sincerely,

					Emmanuel Charpentier
