solver: Set GAMS and GDX library directory

In olugovoy/energyRt: Energy systems modeling toolbox in R, development version

Set GAMS and GDX library directory

Description

This (optional) function sets path to GAMS directory to R-options. It might be useful if for the cases when several different version (and licenses) of GAMS installed, to easily switch between them. It is also possible to set different path for GAMS and GAMS Data Exchange (GDX) libraries. If GDX path is not set, the GAMS path will be used. If GAMS path is not set, the default system GAMS-path (OS environment variables) instead.

Usage

set_gams_path(path = NULL)

get_gams_path()

set_gdxlib_path(path = NULL)

get_gdxlib_path()

set_glpk_path(path = NULL)

get_glpk_path()

set_julia_path(path = NULL)

get_julia_path()

set_python_path(path = NULL)

get_python_path()

Arguments

path	character path to the python installation. If NULL, the global operation path is used.

Value

Sets path to GAMS library in R-options

The current path to GAMS library, set in R-options

Sets path to GDX library in R-options

The current path to GDX library, set in R-options

sets the path to the GLPK library in R options and returns NULL.

returns the path to the GLPK library.

Sets the path to Julia installation in the energyRt environment options and returns NULL.

character. Path to Julia installation.

Writes or reads the path to python installation or environment to/from energyRt options.
