Creates the graphical layout of resultant A-, MV-, D- or E-optimal or near-optimal row-column design on a separate pop-up GUI tcltk window.

`trt.N` |
integer, specifying number of treatments, |

`col.N` |
integer, specifying number of arrays, |

`theta` |
numeric, representing a function of the ratio of random array variance and random error variance. It takes any value between 0 and 1, inclusive. |

`OptdesF` |
matrix, a |

`Optcrit` |
character, specifying the optimality criteria to be used. Thus, |

`cbVal2` |
checkbox value. It takes a value of zero or one. The default value of |

R package.

Returns the graphical layout of the resultant optimal or near-optimal row-column design '`OptdesF`

' on a separate pop-up window. Furthermore, the function `graphoptrcd.mae`

saves the graphical layout of the resultant optimal or near-optimal row-column design in .pdf format in a working subdirectory.

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.
