Hi, I have a matrix containing ID numbers in each column. I would like to program function which calculate common number of ID numbers between each pair of columns.
Suppose: 5 6 7 1 5 3 6 7 2 Then the result should be: 0 2 0 2 0 1 0 1 0 The main problem is how to implement intersect() function to walk through each pair of columns and write result to result matrix. Thanks in advance for any suggestion, Andrej ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
