Here is my ugly approach: #This matrix maps a unique id i. 1. If you need all possible combinations of 14 values of 1 and 0, it's like generating all possible numbers from 0 to (2^14)-1 and keeping the binary representation of them. crossing () is a wrapper around expand_grid () that de-duplicates and sorts its inputs; nesting () is a helper that only finds combinations already present in the data. Here's a quick and dirty way of generating random X and Y values without repeats that are in your grid. Timings are excellent for small to moderate values of m, up to about 10,000, but degrade for larger problems. Place layer below selected layer.

There are probably much more efficient methods than. For a two-variable problem, outer is most likely the best solution for this and if the space to loop over is small enough then we can have expand. Choose the following settings in the random number generator: Min = 1. grid in vector. data. Both of these can be controlled with plot_layout () p1 + p2 + p3 + p4 + plot_layout (ncol = 3) p1 + p2 + p3 + p4 + plot_layout (widths = c (2, 1)) When grid sizes are given as a numeric, it will define the relative sizing of the panels.
