Dear R'rs, is there a function that checks if a given vector contains a certain value. E.g.,

a closer look to the help on predict.glm will reveal that the function accepts a 'type' argument. In you case 'type = response' will give you the results in probabilities (that it seems to be what you are looking for). There also is an example on use of the 'type' argument at the end of the page.

Appologies if this is a simple problem. I have a matrix which is 86x3 and each row contains three integers. The problem I have is that some of the rows of integers are repeated in other rows and I only wish to have one copy of these rows. Is there a function that I can use which will identify these repeated rows and delete them from the matrix? I have searched for help with this problem but the

I have a matrix such as this, [,1] [,2] [,3] [1,] 1 1 2 [2,] 2 5 5 and a larger matrix such as this, a b [1,] 1 5 [2,] 2 5 [3,] 4 9 [4,] 5 8 [5,] 7 8 [6,] 7 10 [7,] 9 10 what I want to do is check the number of times the columns in the first matrix appear as rows in the second matrix. So for instance in this example 1,5 and 2,5 appear in both so I'd want

I have 2 matrices. One which contains a complete set of row combinations. Another which contains a subset of the first. What I would like to extract is the rows which are in the first but not repeated in the second. For instance if the following were my two matrices, A [,1] [,2] [,3] [,4] [1,] 1 2 3 4 [2,] 1 2 3 5 [3,] 1 2 3 6 [4,] 1 2 3
