Rserve is a binary R server that listens to clients and processes
their requests. The Rserve package primarity builds the server which
can be the started using R CMD Rserve or via the Rserve() function in
R.
Clients programs that connect to a running Rserve and submit requests
for computation. The Rserve protocol is open source, so anyone is free
to write a client, but Rserve package comes with three clients:
- Java client in src/client/java
- C++ client in src/client
- simple R client part of the Rserve R package
Java client
=============
The most sophisticated client is the Java client which allows any Java
application to use R facilities without linking directly to R. It
supports the full range of Rserve functionality and is located in
src/client/java
It can be compiled into a JAR file by typing "make" in the
src/client/java directory. The resulting file JRcleint.jar is all that
is needed. JavaDoc documentation can be generated using "make doc".
C++ client
============
The C++ client is located in the src/client directory and will be
compiled if --with-client is specified upon installation.
Alternatively it can be compiled manually by typing "make" in
src/client after configure script was run. See ReadMe.txt in
src/client for details.
R client
==========
The Rserve package also includes a simple R client, i.e. it allows you
to connect to Rserve from R itself. It is very simple and limited,
because Rserve was not primarily meant for R-to-R communication (there
are better ways to do that), but it is useful for quick interactive
connection to an Rserve farm. See ?RSconnect in R after loading the
Rserve package.
