You should have four files: this "installation-S-info.txt" file, and the
files "combo.f", "usage-info.txt", and "Splus_code".  The file "combo.f"
contains Fortran programs which are designed to be called from within
Splus.  The file "Splus_code" contains Splus functions.  To use these
programs, carry out the following three steps.

1. Compile the program "combo.f" with the -c option (compile, but do not
   link) via the command:

   f77 -c combo.f
   or
   f90 -c combo.f

   This should create an object file named "combo.o"

2. Start Splus and then read in the required Splus code using:

   source("Splus_code")

3. Load the Fortran program into Splus using either dyn.open(),
   dyn.load(), dyn.load2(), dyn.load.shared(), or static loading with
   LOAD.  The method used depends on what is available or preferred on
   your system.  These are illustrated below.  Our experience is with
   Unix-type systems.

   In the new version of S (version 6) you execute:

   dyn.open("combo.o")

   In older versions of Splus/S, you do one of the following.

   If dyn.load() or dyn.load2() are available, then after starting Splus
   you execute either:

   dyn.load("combo.o") or dyn.load2("combo.o")

   If dyn.load2() does not work for you, you may have to use the size
   option and do something like this:

   dyn.load2("combo.o", size=250000)

   If dyn.load.shared() is available, you issue the Unix command:

   Splus SHLIB -o combo.so combo.o

   Then you start Splus and execute the command:

   dyn.load.shared("./combo.so")

   If none of the above are available, you must use static loading as
   follows.  Issue the Unix command:

   Splus LOAD combo.o

   This creates a local version of Splus named local.Sqpe in the current
   directory.  This local version contains the Fortran subroutines in
   combo.  If you execute Splus in this directory, the local version
   will be used.
















Usage
-----
The following example should work in windows and also in Unix, if
installed by root (else see below).

library("npbayes")
data(ovarian)
ovarian.dat <- cbind(ovarian$futime, ovarian$fustat)
ovarian.1000 <- gibbs1(data=ovarian.dat, prior=c(.1,.1,1000), nrep=10000)
plot(ovarian.1000)
summary(ovarian.1000)


In Unix, if you installed in a local directory, instead of
'library("npbayes")' you do:

library("npbayes", lib.loc="./lib")
dyn.load("./lib/npbayes/libs/npbayes.so")
