The point is that literate format has special meaning. If format is literate
then tex2lyx does translation in a bit special way:
- parsing of code chunks to scrap style
- choice of literate-* layouts
Additionally, view/export is done as:
1. export to noweb format, which is LaTeX with
<<chunk>>=
...
@
parts and of course \usepackage{noweb} in preamble
2. weaving with defined weaver to get LaTeX
3. further on
I "want/think" that additional option would be the easiest way since it is
easier to hack in another set of layouts say sweave-* as based on literate-*.
I have been working on this styles for last month and there are some additions
that I would like to see in sweave-* layouts. This could also be done as a copy
step between literate and sweave, but would this cause also change of layout
i.e. say from literate-article to sweave-article? If yes OK, but note that the
other way around i.e. sweave --> literate is not what I want as literate will
put \usepackage{noweb}, while I want \usepackage{Sweave} + some other nifty
stuff. Having another format, say sweave instead of literate, would ease the
converters part.

The point is that literate behaves differently than latex format as noted above.
After one month of thinking and tweaking the layout files I think that direct
support of Sweave in LyX would really be great and I am realising that probably
only minor changes/additions are needed. The needed structure is already in LyX.
What is needed is option to use this structure just a bit differently - to use
literate-* layouts or sweave-* layouts. I would suggest -l option to tex2lyx
instead of -n as -n is specific to noweb. -l option would also accept literate
paradigm, default would be noweb, but with possibility for sweave i.e.
tex2lyx -l file.nw
tex2lyx -l sweave file.Rnw
I already have sweave-*.layout file, working preferences (configure.py could
be easily enriched with this) and additions to syntax.default (already in).
Thanks and happy new year!
