SYNOPSIS

  inherit R

DESCRIPTION

R is a GNU implementation of S, a language and environment for statistical computing and graphics.

The primary purpose of R.cygclass is for creating Cygwin packages from CRAN packages, the R equivalent of Perl's CPAN. CRAN package builds are driven by R itself.

Most CRAN packages build OOTB, but creating a Cygwin package may be helpful if a patch is required or if the build requirements are substantial (e.g. RGtk2, the GTK+ bindings which are used in several GUIs). When using R.cygclass to build a CRAN package, NAME must be "R-" followed by the CRAN package name. In most such cases, the R.cygclass src_compile and src_install should suffice.

Alternatively, the definitions in this cygclass can be used to help build an R-dependent package which does not use CRAN, e.g. rkward.

  R_CONFIGURE_ARGS="arg1 [arg2 ...]"

DESCRIPTION

A string containing flag(s) to be passed to the configure script used by module packages containing native code.

R_compile

[ Top ] [ R.cygclass ] [ Compile Functions ]

SYNOPSIS

  cd $B
  R_compile

DESCRIPTION

Configures and compiles an R module packages. Due to the nature of CRAN packages, the package is not compiled in B, but is compiled and "installed" into a temporary directory.

R_install

SYNOPSIS

  R_install

DESCRIPTION

Installs the R module into $D. Due to the nature of CRAN packages, all this does is copy from the temporary directory used in R_compile.
