binmat {hyperdirichlet} | R Documentation |
Create a matrix of all binary combinations for use with the hyperdirichlet distribution
binmat(n, alternatives = NULL, pnames=NULL)
n |
Number of binary digits |
alternatives |
The alternatives; prototypically TRUE and
FALSE , but default NULL , taken to mean 0 and
1 , is easier on
the eye |
pnames |
Optional vector specifying the column names; default of
NULL means to use p1 ,p2 etc |
Function binmat(n)
returns an integer matrix of zeros and ones
with 2^n rows and n columns. In binary, the rows count
from 0 to 2^n-1.
