Description Usage Arguments Value Author(s) See Also Examples

View source: R/makeBlkDesMat.R

Description

Construct a binary matrix representing the block design. The rows are corresponding to the observations and the columns are corresponding to the blocks.

Usage

1
makeBlkDesMat(design.df, blkTerm)

Arguments

design.df

a data frame containing the experimental design. Requires every column be a factor.

blkTerm

a vector of character containing the labels of the block terms in the model generated by the terms.

Value

A list of the binary matrices.
