The R-Commander plugin RcmdrPlugin.DoE is on CRAN as a beta version; if you use a version before 0.6, please upgrade, as error message handling has substantially improved with version 0.6.

The R-Commander plugin RcmdrPlugin.DoE

• provides a graphical user interface (GUI) for much of the packages' functionality, so that the methodology becomes usable for people who are not willing to learn how to program R code;
  look here for instructions on how to get going if you are not familiar with R. (I have checked these instructions for Windows and MaxOS X (Snow Leopard). If you are on Linux, you are partly on your own, since I have no experience with installation of R-packages for Linux systems; there may be extra steps involved.)
• is based on the R-commander
• is still in beta shape. While the package has undergone some testing by myself, it is very likely that it does still have some bugs that are only found when using certain menus in an as yet untested order or under other circumstances that I failed to consider. Testing a GUI is particularly cumbersome, therefore I want to strongly encourage those who undertake it to work with this beta version to report anything that appears to be a bug or unexpected behavior.
  Wishes are of course also very welcome.
• As with all R packages licensed under GPL 2, it is of course also true here and is emphasized in order to make it very clear that you need to be particularly cautious in applying the current beta version of the software: BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

The most important future developments:

• incorporate feedback from beta testers
• implementation of new optimal column choice features for general orthogonal arrays
• incorporation of D-optimal designs (pending incorporation of these in
  DoE.wrapper)
• incorporation of further designs for computer experiments (pending incorporation of these in
  DoE.wrapper)
• more flexibility for blocked regular 2-level fractional factorial designs
• implementation of split-plot designs
• improve help / write step-by-step documentation
• polish the GUI w.r.t. to consistency, until internationalization makes sense
