How to get the latest package version installed on older R versions
The packages in the DoE project are currently updated quite frequently. If you are not at least on version 2.9.0 of R, automatic installation from the Windows GUI or with function install.packages with the default settings will not find all relevant packages or install old versions.
It may be wisest to update your version of R, although I know it does seem like a real nuisance (see FAQ http://cran.r-project.org/bin/windows/base/rw-FAQ.html#What_0027s-the-best-way-to-upgrade_003f on how to do that).
If you have reasons to not update yet, and are not running the latest release of R (starting with 2.9) but a recent R version (at least 2.8.0, with older versions some functions will produce errors), you can load the latest versions of the DoE packages by using option contriburl in install.packages to set the repository to the newest R-version, as in the following example:
install.packages("DoE.base", contriburl = "http://cran.r-project.org/bin/windows/contrib/2.9")
It is recommended to replace the "cran.r-project.org" with the URL for a mirror close to you. I have done limited testing on whether this works OK. However, be warned that I have no way of knowing whether there is something specific about your combination of R packages that makes mixing R versions mess up some things for you.P.S.: If you are really keen on getting a new version early, use the Austrian server. But of course, if we all use it at all times, it will not work very well ...
