Building LOCFIT for S-Plus versions 5 and 6.

The installation below is designed for S-Plus versions 5 and 6. For S-Plus 5.0 and 5.1 on some platforms, the library installation is broken, so the compilation may not work. S-Plus 6 seems more reliable.

For pre-compiled versions of LOCFIT, see the binaries page.

Download and save the LOCFIT source archive. To make Locfit available to all users on your system, save the archive in $SHOME/library.

Unpack the archive:

      gunzip locfit.tgz
      tar -xvf locfit.tar
      cd locfit

Do NOT run Splus5 CHAPTER in the locfit directory.

Ensure the SHOME environment variable is properly set.
If you do not invoke S-Plus with the command Splus5, you'll need to edit the definition of SPLUS in the install.S5 file. S-Plus 6 users: this is important!
Run the S-Plus 5 installation script:
```
      ./install.S5
```
This should make some subdirectories, and compile the necessary source files.
If S-Plus is started in the installation directory, Locfit is available automatically. If S-Plus is started in another directory, attach the library with
```
> library("locfit",first=T)
```
(use a lib.loc argument if necessary).

(Optional) Add the line

      locfit       Local Regression and Likelihood

to the file $SHOME/library/README.
