Hey eveyone! I hope someone can help wiht this question. I have a matirux of all zeros and ones and I would like to indentify all unique patterns in the rows andthe number of times the pattern occurs. I changed all zeros to NA tried to use prelim.norm to identify all patterns of missing data in the rows. I got the message    

  Warning message:
NAs introduced by coercion

  Any ideas of how to get this to work? Or are there any way to indentify all the unique patterns in a huge matrix? ( 10000 x 71)    

  Thanks for any suggestions!!
