CombS {CombinS}  R Documentation 
The Combinatory Method (s) for the construction of rectangular PBIB designs
Description
The application of the Combinatory Method (s), with s
chosen in [2, l1]
,
on rectangular association scheme to obtain the configuration and the
parameters of the PBIB
design associated.
Usage
CombS(n, l, s)
Arguments
n 
Number of lines of the association schemes array. 
l 
Number of columns of the association schemes array. 
s 
Number of the token treatments from the same row of the association scheme. 
Details
For
2 < s < l
, we obtain a rectangular PBIB design.For
s = l
, we obtain a singular group divisible designs.
Value
A LIST :

PBIB
The configuration of the PBIB. 
Type
The type of the design 
V
Number of treatments. 
B
Number of blocs. 
R
Repetition of each treatment. 
K
Size of blocs. 
lamda
Vector of mlambda. 
Resolvable
Is the design Resolvable ?
