R help - Nov 1998 - dyn.load and/or add new package (Windows 98)

Hi,

I have been trying to dyn.load a library (rq.obj), which will allow me to run
a quantile regression function, but so far unsuccessfully.
I have tried under windows 98 and R 6.24:

1) dyn.load("d:\\...\\rq.obj")
2) dyn.load("d:\...\rq.obj")
3) 1 and 2 accounting for case sensitivity.
4) dyn.load("d:/.../rq.obj")
5) Place the files in the directory where from I start R and then issue the
   command dyn.load("rq.obj").

One way or the other I always get the following error message:

Error in dyn.load(x) : unable to load shared library
"D:\Documents\rq.obj"

NOTE: According to the FAQ, Add-on Packages can only be added under Unix, or at
least, the information there is only for Unix. Is that so, or is it possible
to do it under Windows 98? I am a newbie, but I believe that I have a package
since it contains several files with extensions .s, .r, .q  and so on.
This quantile regression package was prepared by Prof. Roger Koenker for 
Windows (he uses Unix).

Has this happened to you? Any ideas? I would really appreciate your help.

Thanks a zillion,


Alvaro Novo

I also have planned to get Koenker's quantile regression functions to
work under R (Windows), but cannot find something which understands
ratfor.  If anyone can point me to that, I'll give it a try soon.

Specifically to the Q's:

1) dyn.load("d:\\...\\rq.obj")
> 2) dyn.load("d:\...\rq.obj")
Trying to lode the code compiled for S is optimistic, I beleave
that to be 16-bit DLL's which R will not understand. They must
be recompiled, which is easy, given that the ratfor problem can be
solved.

In R, you can only dyn.load dll files, not obj files.  In addition they
have to be built with the Mingw32 compiler (either directly on a Win9*
system, or cross-compiled from a unix system).  Even then, there is a
bug in Win9* built dll's which may prevent dynamic loading (cross-
compiled OK).  See Guido's help file for more information on building
dll's.

Perhaps you are confusing R with S+ where an obj file can be dynamically
loaded with dyn.load, provided the obj file was created with the Watcom
10.* compiler.

Did he design it for use with R on a Windows system ?  What compiler did
he use ?
