rmvbin
(Package: bindata) :
Multivariate Binary Random Variates
Creates correlated multivariate binary random variables by thresholding a normal distribution. The correlations of the components can be specified either as common probabilities, correlation matrix of the binary distribution, or covariance matrix of the normal distribution.

check.commonprob
(Package: bindata) :
Check Joint Binary Probabilities
The main diagonal elements commonprob[i,i] are interpreted as probabilities p(A_i) that a binary variable A_i equals 1. The off-diagonal elements commonprob[i,j] are the probabilities p(A_iA_j) that both A_i and A_j are 1.
