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

ROBNRM is a set of programs for the computation of M-estimates of the parameters of
the gaussian and lognormal distribution. As ROBNRM requires ROBETH, before installing
ROBNRM you need to install ROBETH. ROBNRM is available at the URL: 

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

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

    nrmwin.exe     (object files, self extracting zip file; july 2003)
    nrmwin_v6.exe  (the same file but for Splus 6.x;        november 2002)
    nrmman.exe     (manual, self extracting ps-file;        july 2003)

(b) For R (version >= 1.5.1) / Windows, copy the following file in a temporary 
    directory
    nrmR_win.exe   (DLL+source, self extracting zip file; july 2003)
    nrmman.exe     (manual, self extracting ps-file;      july 2003)

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

    nrmsrc.tar.Z   (program sources, compressed; november 2002)
    nrmman.tar.Z   (manual, compresses ps files; august   1999)

Installation
------------
Splus or R under Windows:

1. Execute the self-extracting file 

   nrmwin.exe (or nrmwin_v6.exe for Splus 6.x or nrmR_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
   
   Same procedure for the file nrmman.exe (S-Plus only).

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

2. To invoke the library 
   a) under Splus, use the Splus commands:

   > library(robeth,T)
   > library(robnrm,T)

   b) under R, use the R commands:
   > library(robeth)
   > library(robnrm) 

Under UNIX:

The installation of ROBNRM follows the general ROBETH installation procedure described
in the ROBETH file README/genral.txt. If you have write access to the Splus HOME directory,
the most convenient way to install ROBNRM is the creation of a public libray. 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 robnrm. Type:

   mkdir robnrm

3. Decompress the tar file:

   cd robnrm 
   zcat <your.path>/nrmsrc.tar.Z  | tar xvf -

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

   mkdir .Data      (as a sub-directory of robnrm)
   Splus
   > data.restore("<your.path>/robnrm.dmp")
   > q()

   If your Splus version is 5.0 or higher, step 4 and 5 (compilation) are
   achieved by typing:
   
    Splus CHAPTER
    Splus make
#   If not yet done type: 
#   Splus
#   > source("megauss.q")
#   > source("asvar.q")
#   > source("table.q")
#   > source("qntrob.q")
#   > q()
    Goto step 6.

5. Compile  and link (ld command) robnrm.f to a file called robnrm. 
   For more details, follow the hints in genral.txt. See also the
   file loadobj.com. 

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

   > library(robeth,T)   
   > library(robnrm,T)

7. 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(robnrm,T)
