planor
Generation of regular fractional factorial designs

What is planor?

planor is a R package dedicated to the automatic generation of regular fractional factorial designs with one or several block systems.

The user invokes first the functions planor.factors and planor.model to describe its experiment. The function planor.designkey searches for a design key in a possibly mixed factorial context. A design from one of the solutions can be built by using planor.design. summary.designkey summarises the design properties from a design key matrix.
Other functions:
- planor.randomize randomizes a factorial design according to a specified block structure formula.
- alias displays the design keys matrices and the factorial effects confounded with the mean.

This package is developed in the Applied Mathematics and Informatics Lab (MIA) of INRA - Jouy-en-Josas, France. It is still under test and must be used with caution.

What is planorR?

planorR is a clone of the planor package, which does not require biganalytics and bigmemory packages but is more limited as to the size of the problems. Windows binary is available.

Authors

André Kobilinsky, Annie Bouvier, and Hervé Monod (MIA, INRA, Jouy-en-Josas, France).
