Gudday, I've had a good look everywhere trying to figure out how to do this, but I'm afraid I can seem to find an answer anywhere - maybe its because I'm not using the right terms, or maybe its because I'm a dummy. But unfortunately, I am not completely and utterly stuck. Here's the problem:
I have two large, six dimensional arrays that I would like to add together. Lets call them f and m. Their dimensions are respectively: > dim(f) [1] 10 25 1 1 1 14 > dim(m) [1] 10 1 1 1 1 14 You can see that they're pretty close in size, but not identical. What I would like to do is expand or inflate m along its second dimension so that it ends up with dimension 10 25 1 1 1 14, so that I can then add the two together - the new values created along that second dimension would simply be copies of the first value.. What's the fastest way to do this? Is there a dedicated function? Ideally I envisage something that you feed the input array, and the desired dimensions, and it does the rest for you. Please also bear in mind that this is a specific problem - the more general case is where I don't know which dimensions are "out of shape", so to speak... I hope that's clear, and that someone can me out here...
