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

ROBGLM is a set of Splus programs for the computation of generalized linear 
model when method is set to "cubinf" in the Splus command "glm". As ROBGLM 
requires ROBETH, before installing ROBGLM you need to install ROBETH. ROBGLM 
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:

    glmwin.exe     (object files, self-extracting zip file;  april 1997)
    glmwin_v6.exe  (the same file but for Splus 6.x;        august 2004)
    glmman.exe     (manual, self-extracting ps and pdf-file; april 1997)


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

    glmR_win.exe   (source, self extracting zip file;    september 2003)
    glmman.exe     (manual, self-extracting ps and pdf-file; april 1997)

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

    glmsrc.tar.Z   (program sources, compressed; april 1997)
    glmman.tar.Z   (manual, compressed ps file;  april 1997)


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

1. Execute the self-extracting file 

   glmwin.exe (or glmR_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 glmman.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(robglm,T)
 
   b) under R, use the R commands:
      > library(robeth)
      > library(robglm) # => Masks some R functions


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

If you have write access to the Splus HOME directory, the most convenient way 
to install ROBGLM 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 robglm. Type:

   mkdir robglm       

3. Decompress the tar file:

   cd robglm  
   zcat <your.path>/glmsrc.tar.Z  | tar xvf -

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

   mkdir .Data      (as a sub-directory of robglm) 
   otherwise (Splus 5.x, Splus 6.x or higher) , type:

    Splus CHAPTER
    Splus
    > source("glmano.q")
    > source("glmcomp.q")
    > source("glmdev.q")
    > source("glmextr.q")
    > source("glmrob.q")
    > source("stglm.q")
    > q()

5. To invoke the public library, open Splus and type:

   > library(robeth,T)   
   > library(robglm,T)
  
6. For a private library, create a file "mylib.q" for example, containing
   the following line:
   assign("lib.loc","<the path to the 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(robglm,T)
