useR's, I have used expand.grid() several times and like the results it gives me. I am now trying something with it that I have not been able to get to work. For any n column matrix I would like to run this function on those n columns and store the results. For example, if my matrix has 1 column then this is just expand.grid(x = column1). If my matrix has two columns, then I want expand.grid(x = column1, y = column2), and so on for any number of columns...
In a program I am writing, the user can specify any matrix. Does anyone know of a way for R to calculate this based on what the input matrix is? e.g. if this user gives a 3 column matrix, I want to be able to perform expand.grid() on these 3 columns without having to hard code it b/c I want to have this small function embedded in my code and the results stored as a variable. If this isn't clear, I can try to be more detailed. Thank you for any thoughts.
