sketch: Utils: Experimental sketch

In AgronomiaR/AgroR: Experimental Statistics and Graphics for Agricultural Sciences

Description

Experimental sketching function

Usage

sketch(trat, trat1 = NULL, trat2 = NULL, r, design = "dic", pos = "line")

Arguments

trat	Vector with factor A levels
trat1	Vector with levels of factor B (Set to NULL if not factorial or psub)
trat2	Vector with levels of factor C (Set to NULL if not factorial)
r	Number of repetitions
design	Experimental design ("dic", "dbc", "dql","psubdic","psubdbc","fat2dic","fat2dbc")
pos	Repeat position (line or column)

Value

Returns an experimental sketch according to the specified design.

Note

The sketches have only a rectangular shape, and the blocks (in the case of randomized blocks) can be in line or in a column.
