hi I have a matrix (10x10) and I have to perform t tests on each row by considering first 5 elements as data set A and next 5 as data set B. This part is easy, However after one t test on each row, I have to randomly permute each column to get new values for each row and then perform another t.test. I can permute the column randomly using the function sample(x) but i am having problem in fitting this into the matrix to perform t test on the row. I would appreciate if someone can help me with this. Or is there a function to randomly get different matrix from one original matrix without having to deal with different columns? -- View this message in context: http://www.nabble.com/help-needed-tp20648304p20648304.html Sent from the R help mailing list archive at Nabble.com.
