o_addpath: Manipulating Octave Search Path

In RcppOctave: Seamless Interface to Octave -- And Matlab

Description

Adds a directory at the beginning of Octave search path.

o_inpath tells if a directory or files are in Octave path.

Usage

o_addpath(DIR1, ..., OPTION = "-begin")

o_inpath(...)

Arguments

DIR1	path specification to add to Octave search path. See section Octave Documentation.
...	other path specifications
OPTION	option that specifies how the path should be added. Possible values are: '-begin', 0, '-end', 1. See section Octave Documentation.

Details

The .oct files present in directories from the search path are looked up when an object or function is requested but not loaded in the current session. The files are watched and automatically reloaded in case modification.

Value

returns invisibly the old value of search path.
