get_sys_dir: Get GAMS system directory

In iiasa/testGAMS: What the Package Does (One Line, Title Case)

Description

Get the path to the GAMS system directory being used for testing. This is the GAMS installation directory where the GDX libraries and GAMS compiler/interpreter will be loaded from. It therefore determines which GAMS version is used for testing. The GAMS system directory can be set with set_sys_dir().

Usage

get_sys_dir()

Details

When no system directory is set yet, this function will try to get and set a default system directory from an environment variable, first R_GAMS_SYSDIR, and if not available via PATH (on Windows) or LD_LIBRARY_PATH (on Linux). If no such default is available either, this function throws an error.

Value

Path to the in-use GAMS system directory.

Examples

sys_dir <- get_sys_dir()
