R-Package FrF2 (on CRAN already)

• holds large catalogue of regular 2-level fractional factorial designs - further extensions planned
• provides functions FrF2 for design of regular and pb for design of non-regular Fractional Factorial 2-level designs - center points are possible for designs with quantitative factors only
• function FrF2 has many options for creating tailored experiments (request certain 2-factor interactions to be estimable, created blocked or split-plot designs or designs for some hard-to-change-factors)
• provides functions for simple graphical analyses of 2-level Fractional Factorials

Highest priority developments:

• structure code to become more maintenance-friendly
• provide an example-based manual
