What version of Splus are you using?

BETA Release (3.9.7) Download version for Unix and Splus 3.x

BETA Release (3.9.7) Download version for Unix and Splus 5.x or Splus 6.x

The installation and build process for Splus5 or Splus6 is a bit different than for previous versions. Basically one follows the instructions in Chambers, J.M. (1998) Programming with Data, Springer-Verlag: New York on page 233. Here summarised are some instructions.

Note that if you are using Splus 6.x then replace all calls to Splus5 with Splus6 (that is of course if your Splus executable is called Splus5 or Splus6; it might just be called Splus). With Splus6 none of the bugs outlined below occured under Redhat 8.0.

1. Save the gzipped shar file to the directory where you want to create the WaveThresh library. If you have the necessary permissions then go into the S HOME directory ($SHOME) and put the file in the library directory (e.g. ${SHOME}/library.)
2. Gunzip the file. Run the file through sh. E.g. type:
   sh WaveThresh3.9.6v5.shar
   The system unpacks the files into the directory. A subdirectory called WaveThresh is created.
3. cd to the WaveThresh directory.
4. Initialize the Chapter. Type:
   Splus5 CHAPTER
   The last message should be S chapter initialized.
5. (Optional) If you want the C code to be optimised to run faster you might want to add the -O option to the LOCAL_CFLAGS variable in the makefile. To do this edit the makefile, locate the LOCAL_CFLAGS variable (the 6th line down in my makefile) and make it read
   LOCAL_CFLAGS=-O
   
6. The SPlus source code needs to be installed or booted into the _Data directory. Type:
   Splus5 make boot
   You should get the message
   S datasets booted
   if all goes well.
   • Error message on Solaris + Splus 5.0 (and Splus 5.1 apparently)

     There is basically a problem in the makefile. Edit the makefile and find the make section for booting (labelled boot: in the makefile). On the 3rd line after the label you will see an echo line. Change the part at the end which reads
     $(SHOME)/S
     to
     $(SHOME)/cmd/S
     In other words just insert a cmd. Try the
     Splus5 make boot
     command again.)

     You should get the message
     S datasets booted
     if all goes well.

   • Linux & Splus 5.1 Release 1. I got another error message this time.

     /bin/sh: -c: line 2: syntax error: unexpected end of file

     I didn't have the time to figure out exactly what was wrong. However, I did this step manually. Type:

     setenv SHOME /usr/local/splus

     or whatever your SHOME directory is. Then

     setenv BOOTING_S "TRUE"

     I was using tcsh as my shell, csh should be the same. With sh you need to export the variables.

     Then type

     ${SHOME}/cmd/S

     You should get the message
     S datasets booted
     if all goes well.

   • Compile the WaveThresh object code. Type:
     Splus5 make S.so
     There may be a few compiler warnings but an S.so file should be created.
   • That's it. You can now follow the INSTALL+USE file provided in the WaveThresh distribution from Step 3. Basically you can cd to some other directory (where you want to play with your data on a given project). After entering SPlus in this new directory you should be able to issue the command:
     library("WaveThresh")
     to access the software. If you have installed the WaveThresh software in some non-standard place (i.e. not $(SHOME)/library) then you will have to augment the library call with the appropriate lib.loc argument.
