Hello, I have a large matrix (data), in which there is a column offerid. The values are numbers (lets say 1:5) There is another vector (idnew), which contains some of the offerids and many more (3:10). I want a subset of the matrix wiith only those rows, which match the criteria of the vector. How can I make it work? Thanks!
