Note that several features of graphics device in RKWard are already realized
as plugins (e.g. Device->Export..., and Edit->Draw Grid). See
. I'm not sure, what exactly you have in mind, and whether such
"contextualized plugins" are already good enough for your purposes. However,
in principle, I believe it will probably be possible to add the required
support without too much effort.
You may also want to take a look at the CLT-plugins (e.g. Distributions-
>Continuous->Beta->Beta CLT), to get an idea of what can be done with the
plot-preview feature, alone.
Perhaps you can give some more detail?

- The KDE libraries are also available as MSVC-compiled binaries. If you use
"Package Manager" mode in the KDE on Windows installer, you will be able to
select which compiler flavor you want to install.
- I know that the RKWard sources currently use some constructs (esp.
"#warning"-directives), which are not compatible with MSVC in their current
form, so this would need some cleanup, but I don't expect any significant

linking C++-code to R using MSVC. Personally, I have never cared about the
details, so I'm not sure, how big a problem this is, but it is the part that I
would be most worried about.
- You may be interested in our wiki page on compiling on Windows:
As you can see, it is not quite trivial to set up everything, correctly. Quite
likely some steps will need to be adjusted for compiling with MSVC. See
http://techbase.kde.org/Projects/KDE_on_Windows for links to mailing list and
IRC-channel for KDE on Windows, in case you need help with that. I know that
some other KDE-based projects offer MSVC-compiled binaries on Windows, so you
may also be able to get some help, there. E.g. digikam and kmymoney.

Well, I would certainly be glad to have you as a contributor!
P.S.: I'll give you an answer to the questions you asked in private mail, as
soon as I can find some time.
