Creates the graphical layout of resultant optimal design

The function graphoptBbd creates the graphical layout of resultant Bayesian A-, or D-optimal block design on a separate pop-up GUI tcltk window.

Keywords
Graphical layout
Usage
graphoptBbd(trt.N, blk.N, alpha, beta, OptdesF, Optcrit)
Arguments
trt.N

integer, specifying number of treatments, v.

blk.N

integer, specifying number of blocks, b.

alpha

numeric, representing parameter of beta distribution.

beta

numeric, representing parameter of beta distribution.

OptdesF

matrix, a 2 x b obtained Bayesian optimal block design.

Optcrit

character specifying the optimality criteria to be used. Thus, Optcrit takes the letter "A" and "D" for Bayesian A- and D-optimal block designs, respectively.

Details

Detail discussions concerning the constructions of a graphs can be found in igraph R package.

Value

Returns the graphical layout of the resultant Bayesian optimal block design 'OptdesF' on a separate pop-up window. Furthermore, the function saves the graphical layout of the resultant Bayesain optimal block design in .pdf format in a temporary directory.

Note

When closing a pop-up window for graphical layout of the resultant designs (Graph plot), if the window is closed by clicking on the red button with "X" sign (top-right), the warning message "Warning message: In rm(list = cmd, envir = .tkplot.env): object 'tkp …' not found" will occur in R-console irrespective of what command is executed next. To resolve this warning message, click on "close" menu that is located at the top-left of the graph plot pop-up window when closing this window.
