Effect description

Description

There is four ways that effects can be defined in GRD. "factor = slope(s)" will vary the means by an amount of s for each step of the factor; "factor = extent(s)" will vary the means uniformly so that there is a difference of s between the first and the last factor level; "factor = custom(a,b,c..)" will alter each means by an amount of a for the first, b for the second, etc. Finally "factor = Rexpression("R code")" will apply R code to all levels of the factors. R code result alters the base mean.

Usage

slope(s)

extent(s)

custom(...)

Rexpression(str)

Arguments

s

the size of the effect

...

a sequence with the sizes of the effects

str
