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!! Elizabeth Lawson
I think Chuck Celand has pretty well answered it: Don't worry about the warning, since I'm pretty sure it is generated when prelim.norm is calculating something else (e.g. the covariance matrix) and it is not related to generating prelim.norm(X)$r which is the list of patterns and the numbers of times they occur.
