Subject: R-beta: A new port of R to MS Windows on CRAN


Hi,

I've included Guido Masarotto's port of R 0.61.1 to MS Windows 95/NT
in $CRAN/bin/ms-windows-32 ... you can find both the sources and
binaries there.

I include Guido's README below.

Thanks again to Guido for making this port available!

Best,
Fritz Leisch



**********************************************************

rgnwbin.tgz and rgnwsrc.tgz are the first results of an attempt to
build R for Win95 and WinNT using egcs-mingw32.

The advantages over the binaries for MsWindows that can be found in CRAN
are:
1. R seems to run faster. Some simple (perhaps too simple)
   benchmarks point to a 20% gain.
2. The port is based on a more recent version (0.61.1) and it is more
   complete (more "system calls": system, tempfile, unlink, 
   WinExec - to launch applications without waiting for the result;
   support for the standard help system: try help(), help(abline),
   help(line,eda), ?women, data(), library())
3. A new menu item "Stop current computation" make  possible 
   to interupt long computation (but only when  something is printed).
4. Since egcs-mingw32 uses the standard C calling convention, 
   you don't need a Watcom compiler to build dynamic link libraries.
   Indeed, this was my original motivation.
5. It should be easy to use some other gnu-win32 compilers (maybe
   running on a non MsWindows machine). It should be easy to 
   adapt the port to lcc-win32, too.
   
But remember: this is experimental code so
-----------------------------------------------------------------------------
                      USE IT AT YOUR RISK
-----------------------------------------------------------------------------

BINARY DISTRIBUTION
Just unpack rgwnbin.tgz somewhere.
The executable is R.GNW\bin\R.exe. This binary distribution
includes only the standard packages (base+eda+mva+stepfun).

SOURCE DISTRIBUTION
This is an add-on to the R-0.61.1 distribution.
So unpack R-0.61.1.tar.gz somewhere.
Then, from the same directory, unpack rgwnsrc.tgz.
To rebuild the system, go to R-0.61.1/src/gnuwin32.
Then
   > make
should build the standard stuff.
To add a new package, you should
a) download it; 
b) unpack it in the R-0.61.1/src directory.
c) go to the R-0.61.1/src/gnuwin32 directory and type
   > make pkg-xxx
   where xxx is the name of the package.
   You should get the directory R-0.61.1/library/xxx
   and its subdirectory R/ (the r-code) data/ (the 
   data of the package) R/libs (the dynamic link library) and
   the support for the help system (INDEX, TITLE, an updated
   LibIndex). Of course, the data and libs subdirectory
   can be missing.
d) if you want the documentation, you can download 
   the preformatted one.Then  unpack it in the R-0.61.1
   (not in the R-0.61.1/src) directory. If you don't need
   the LaTeX files, remove them.

Note:
(1) Of course, you need a compiler. As I have said I used 
    the egcs-mingw32 one:
    http://www.xraylith.wisc.edu/~khan/software/gnu-win32/
(2) You must also have a GNU make and some standard unix
    command (ls,cat,sed,rm). Furthemore, make and this
    command must be able to overcome the MsDOS limitation
    about the length of a command.
    I used the ones coming with the djgpp compiler.
    According to me, they are the best version for dos and
    windows. You can find it in any SIMTEL mirror.
    If you want, I can make available a small file with
    only the needed tools.
(3) The gnuwin32/Makefile use the g77 Fortran compiler.
    If you don't have it, or if you don't want to use it,
    you can use something like
      > make HAVEG77=NO 
    or
      > make HAVEG77=NO pkg-xxx
    For example, the g77 compiler in egcs-mingw32 was
    not able to compile the fortran code in the acepack package.
    However, I was able to build this package with the command
      > make HAVEG77=NO pkg-acepack
(4) When installing a package, if in R-0.61.1/src/library/xxx/R
    exist a file with name yyy.gnw then this file is used
    and files with name yyy or yyy.somethingelse are
    ignored. In this way, you can configure the R code
    of the package. An example is the base/R/system.gnw
    file.
(5) This is not a developer's distribution. For example, dependences
    are written in a silly way. Furthemore, all the code
    in src/appl/, src/appl-f,..... is compiled.
    No use of the original Makefile is done.
    Hence, you have to start from a cleaned distribution.


BUGS and TODO
(0) The English of this README.
(1) If you exit from the edit windows and this is empty you get a
    segmentation fault. This happens also on my Linux box. So,
    it seem to be a general problem.
(2) The dll's are statically linked with the other R code.
    So they get support for the routines that they need.
    In this way, they work but are big. We should have
    a large R.dll with all the standard code. Then 
    the executable and the dll's should simply import
    from R.dll.
(3) Try and adapt this port to other win32 compiler.
    It should be easy. So, why don't try?
(4) The system command does not work if the command to be
    execute require some user interaction. It is just a 
    "simulated  reading pipe for a broken OS".
(5) I inserted an event loop at the beginning of the
    function which print to the console. In this way,
    you can interupt the computation or, for example,
    give the focus to the graphics window.
    But only when you print. A call to the event loop
    must be inserted inside the "main" code.
    But, for the moment, I decided to leave the "main"
    code untouched.
(6) When building package xxx, all the C and Fortran files
    found in library/xxx/src (or library/xxx/src-c if
    you don't have the g77 compiler) are compiled
    and putted in a dll. On the contrary, we have to make
    use of the original Makefile.
(7) The Windows code must be cleaned.
