Description Usage Arguments Value Note Author(s) See Also Examples

Description

Function to do display an alias table for the aliased effects of a fractional factorial design.

Usage

1
aliasTable(fdo, degree, show = TRUE)

Arguments

fdo

needs to be an object of class facDesign.

degree

numeric giving the degree of interaction i.e. degree=3 means up to threeway interactions.

show

a logigal value specifying whether the alias table should be shown or not.
By default show is set to ‘TRUE’.

Value

The function aliasTable() returns a matrix indicating the aliased effects.

Note

For a more detailed example which shows the effect of applying aliasTable() to an object of class facDesign, please read the vignette for the package qualityTools at http://www.r-qualitytools.org/html/Improve.html.
