1) More than one year ago, hence, maybe, things are changed, I download
RSXNT. However, I had problems to run its demo under MsWin3.1 (not under
Win95). So, I prefered to give up. Just a limited experience, however.
The other problem that I see is that, if I understand well,
RSXNT is the effort of just one pearson not of a team.
2) What about DOS? Do you think that we really need a GUI console under
Microsoft-something? A couple of week ago, I took a look to the
R code thinking to recompile it with DJGPP. I didn't try but it seems
possible. The advantages that I can see are:
a) DJGPP is stable, mature and supported.
b) I have limited experence but dynamic linking with DJGPP works
better than under Windows. For me, of course. And I am not a
Windows programmers. But, I was able to to build dyn. libs
which call routines in the main executable (and we need this
non only for call_R but also for R_alloc and S_alloc).
With, just 3 #define's its possible to use the dlopen/dlsym/dlclose
c) Same user interface under MsWindows and Unix (character+readline).
d) DJGPP has g77.
e) From DOS to WinNt, only one executable.
A couple of disadvantages are:
a) Old fashion.
b) We need a new device. I suggest one based on grx (the standard djgpp
graphic library) since this will have a small side effect:
grx is available also for the linux console so can be used under
linux without X (I remember some question about this on
the R mailing list).
c) dll's must be built using djgpp; anyway, djgpp is GPL.
Comments? I have no time for a couple of weeks, but, after, if you
think that can be a worth tentative, I can make the first
attempt (manage to recompile the non-graphic part +
write a first draft for the graphic device if the previous
point go well).
