Functions Useful in the Design and ANOVA of Experiments


The content falls into the following groupings: (i) Data, (ii) Factor manipulation functions, (iii) Design functions, (iv) ANOVA functions, (v) Matrix functions, (vi) Projector and canonical efficiency functions, and (vii) Miscellaneous functions. There is a vignette describing how to use the design functions for randomizing and assessing designs available as a vignette called 'DesignNotes'. The ANOVA functions facilitate the extraction of information when the 'Error' function has been used in the call to 'aov'. The package 'dae' can also be installed from <http://chris.brien.name/rpackages/>.

and each of whose values are either generated within
those of the level of nesting.fac or using the values
of a nested.fac
fac.nested Creates a factor, the nested factor, whose values are
generated within those of a nesting factor
fac.recast Recasts a factor by modifying the values in the factor vector
and/or the levels attribute, possibly combining
some levels into a single level.

values in a vector. (May be deprecated in future.)

strings into several factors.

strings, into several factors using the separated strings.
