planor
Generation of regular fractional factorial designs |
---|
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 MaIAGE research laboratory, INRA.
