Dear list, 

Hello to everybody, I´m interested in finding a package for statistical analysis of binary data, I have a matrix with the following structure: 

Case1 Case2 Case 3 ....... CaseX Control1 Control2 Control3 ....... ControlY 
Pep1 1 0 1 1 0 0 0 1 
Pep2 1 1 1 1 1 0 0 1 
Pep3 0 1 1 1 1 0 0 1 
... 
Pepz 1 1 1 1 1 0 0 1 

I would like to know some R package to calculte similarity matrix or to make some statistical diferences between cases and controls 
Any help it would be very appreciated 

BW
