To build and install
====================

1) (Windows only; required to build but not to install an already
   built SJava) Install the R Windows development tools, as described
   in the R Installation and Administration manual. Set an environment
   variable R_HOME, using c:/Progra~1/ -style file names

2) Install the Java Development Kit (in addition to the Java Runtime
   Environment) and ensure that the JAVA_HOME environment variable is
   set correctly.

3) Check that R understands the location of Java, with

      R CMD config JAVA_HOME
      R CMD config JAVA_LIBS
      R CMD config JAVA_CPPFLAGS

   It may be necessary to run

      R CMD javareconf

   or similar; see the R Installation and Administration Manual for
   further assistance.

4) Build and install SJava with the command

      R CMD INSTALL --clean SJava

   or

      source("http://bioconductor.org/biocLite.R")
      biocLite("SJava")
