guiMode {GroupSeq}R Documentation

creates a GUI

Description

This Function creates a GUI where user can choose one of four Tasks to perform computations related to group sequential boundaries using the spending functions.

There are the following four options which compute:
-1- bounds given analysis times and a spending function;
-2- drift parameters corresponding to given power and bounds;
-3- probabilities given times, bounds and drift parameters;
-4- a confidence interval given times, bounds and final test statistic value.

Usage

guiMode()

Details

The GUI is build within the Tcl/Tk interface of R. I attended to only use the standard Tcl/Tk package, to keep as much compatibility as possible. So you won´t have to install additional Tcl/Tk packages which might cause problems sometimes. Moreover the GUI should work on all platforms.

Each task and calculation will open in a new window with possibilty to save results into a *.html File. So you are able to multitask and to compare results directly and decide which of them you want to save.

Note

This function is meant to be called in context of using groupseq groupseq() does the same and is recommended
