Generate images using Fourier descriptors.
The FourierDescriptors package provides methods for
creating, manipulating and visualizing Fourier descriptors, a
representational scheme used to describe closer planar
contours. The images most easily described using Fourier
descriptors are useful as stimuli for experiments in psychology
and neuroscience.

Package for analysing Fractional Factorial designs with 2-level factors
This package analyses Fractional Factorial designs with 2-level factors; it is meant for completely aliased designs only, i.e. e.g. not for analysing Plackett-Burman designs with interactions. The package enables convenient main effects and interaction plots for all factors simultaneously and offers an enhanced DanielPlot function (modified from BsMD). Furthermore, the alias structure for Fractional Factorial 2-level designs is output in a more readable format than with the built-in function alias.

The package enables convenient main effects and interaction plots for all factors simultaneously and offers a cube plot for looking at the simultaneous effects of three factors. An enhanced DanielPlot function (modified from BsMD) is provided.

Fractional Factorial designs with 2-level factors
This package creates regular and non-regular Fractional
Factorial designs. Furthermore, analysis tools for Fractional
Factorial designs with 2-level factors are offered (main
effects and interaction plots for all factors simultaneously,
cube plot for looking at the simultaneous effects of three
factors, full or half normal plot, alias structure in a more
readable format than with the built-in function alias). The
package is currently subject to intensive development;
structures and even function names may change in the future.
