Design matrices of period balanced incomplete block designs
Description
This function returns the ‘design’ matrix of incomplete
block designs described by Chow & Liu. The design matrices were
recoded 1=R, 2=T1, 3=T2, ...
Usage
bib.CL(trt, p)
Arguments
trt
Number of treatments (3 to 5).
p
Number of periods (2 to trt-1).
Value
Matrix containing the sequences in rows and periods in columns.
The entry (i, j) of the matrix corresponds to the treatment or
dose (index) a subject within i-th sequence gets in the
j-th period.

Examples
# 4 treatments/doses, 3 periods
bib.CL(4, 3)
# gives 4 sequences
# to see this in Chow & Liu's coding
tmt <- c("R", "T1", "T2", "T3")
matrix(tmt[bib.CL(4, 3)], ncol=3)
