         Downloading and installing HUBER and its interface to Splus
********************************************************************************

HUBER is a library of S functions for the computation of "Huber" type robust regression.
HUBER requires ROBETH to be loaded into S-Plus. HUBER is available at the URL:

           http://www.iumsp.ch/Unites/us/msp_us.htm (=> software)

Downloading
-----------
(a) For Splus 4.x, Splus 2000 or Splus 6.x/Windows, copy the following files
    in a temporary directory:

    hubwin.exe     (object files, self-extracting zip file;  july   1998)
    hubwin_v6.exe  (the same file but for Splus 6.x;         august 2004)
    hubman.exe     (manual, self-extracting ps and pdf-file; august 1999)

(b) For R (version >= 1.5.1) / Windows, copy the following file in a temporary
    directory

    hubR_win.exe   (source, self extracting zip file;        august 2003)
    hubman.exe     (manual, self-extracting ps and pdf-file; august 1999)

(c) For Splus 3.1/UNIX (and more recent versions) copy the following files
    in the temporary directory noted <temp.path> below :

    hubsrc.tar.Z   (program sources, compressed; april 1997)
    hubman.tar.Z   (manual, compressed ps file;  april 1997)

I) Installation for Splus or R under Windows:
---------------------------------------------

1. Execute the self-extracting file 

   hubwin.exe (or hubR_win.exe for R)
   
   The name of the directory where the file will be "unzipped" must 
   be entered. For a standard installation, it is:

             c:\Program Files\sp2000\library 
   or      
             c:\Program Files\splus6\library
   or
             c:\Program Files\R\rwNNN\library

   This path is noted <your.path> afterwards.
   
   Same procedure for the file hubman.exe (S-Plus only).

   Remark: Installation for Splus 3.x/Windows is no more available.  

   
   If your Splus version is 4.x or 2000 goto step 2.
 
 
2. To invoke the library 
   a) under Splus, use the Splus commands:
      > library(robeth,T) 
      > library(Huber,T)
 
   b) under R, use the R commands:
      > library(robeth)
      > library(Huber) # => Masks some R functions

II) Installation under UNIX:
---------------------------

If you have write access to the Splus HOME directory, the most convenient way 
to install HUBER is the creation of a public library. Otherwise create your
private library and skip step 1 below.

1. Change to the Splus HOME directory:

   cd <your Splus HOME dir>/library

2. Create the new directory Huber. Type:

   mkdir Huber       

3. Decompress the tar file:

   cd Huber  
   zcat <temp.path>/hubsrc.tar.Z  | tar xvf -

4. Create the Huber/.Data sub-directory and the Splus objects. 

   If your Splus version is 4.x or lower, type:

     mkdir .Data      

   otherwise (Splus 5.x, Splus 6.x or higher) , type:

     Splus CHAPTER

   Then, type the commands:
   Splus
   > source("hubano.q")
   > source("hubcomp.q")
   > source("hubextr.q")
   > source(hubreg.q")
   > source("sthub.q")
   > q()
      
5. To invoke the public library, open Splus and type:

   > library(robeth,T)   
   > library(Huber,T)
  
6. For a private library, create a file "mylib.q" for example, containing
   the following line:
   assign("lib.loc","<the path to the private library>",frame=0)
   In my case, I have: assign("lib.loc", "/users/arandria", frame=0)
   Then after opening Splus, type:

   > source("mylib.q")
   > library(robeth,T)
   > library(Huber,T)
