Start up the dialog handling system

DESCRIPTION:

Starts an external process to handle interactions with various X Window System dialogs. These dialogs are constructed via calls to dialog.create and displayed via dialog.display calls.

Note: This function is deprecated. For more information, see .

USAGE:

dialog.start(args, gui=options("gui")[[1]]) 

OPTIONAL ARGUMENTS:

args
a vector of character strings to customize the look of the dialogs. The strings are equivalent to the command line arguments used to start other X11 programs. For example, "-display mach:0.0" could be specified to display windows on screen 0 of machs display.
gui
character string giving the name of the graphical user interface that should be used. Currently, "motif" is the only supported value.

SIDE EFFECTS:

dialog.start turns on the dialog handling system.

DETAILS:

This involves the starting of another process (e.g. sdlgMotif). It also changes a data set (stored in the session database) that is used to maintain some information necessary to communicate with the external process.

The dialog handling system is composed of some S language functions, some C language code that is loaded into S-PLUS, and an external process. The external process accepts some simple line-oriented commands from S-PLUS via the dialog.* functions, and returns information in a similar manner.
