consoleMode

This function provides the user interface in an interactive mode.
It gets the necessary parameters by the user from the R console in case
the gui does not work properly or user is a console fan ;-)
 
User inputs option, analysis times, spending function or bounds,
truncation value for bounds, optional drift parameters, power, 
or confidence level.

methods

The computations are done with the alpha spending approach. Therefore
	interim analyses need not to be equally spaced, and their number need not to be specified in advance. 
	It is appropriate for any trial based on normally distributed test statistics with independent increments,
	survival studies, and certain longitudinal designs.
	Among other things it computes boundaries, power, drift and confidence intervals.
	The package provides this in a GUI and user has option of graphical output of the results
	and saving them into .html files.
