In modern-day China, red continues to stand for good fortune and wealth, with people gifting money in small red envelopes during Chinese New Year. 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. Maybe we can use expand.grid in the following way. Remember, the formula to calculate combinations is nCr = n! However, the probability that monkeys filling the entire observable universe . The signature of the method looks like cobn (items, k). 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. Now, if we want to run the code for this array, some combinations will be repeated. This is especially important in data pipelines where future processes might expect there to be length (unique (cyl)) * length (unique (gear)) rows in the dataset. Click on Go, then wait for combinations to load. tidyr::complete() can also be used similar to expand.grid(). In this method, well pick an element then find a combination of r-1 elements. ncr = n-1cr + n-1cr-1Following is implementation of method 2. combinations with replacement factorial The product of an integer and all the integers below it Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, infravalued method as per its speed in comparison to the well known expand.grid, This is nice (+1), and it's nice to see it using built-in functions. Notice here how a more complex problem (solving N) is naturally decomposed to a simpler problem (solving N-1). I suggest this solution: it does not use any other library than base. Let the input array be {1, 2, 3, 4, 5} and r be 3. Thus I have 1,000 numbers or 1,000 possible combinations. RDocumentation. So, if we take "R," then with R, we can take G, Y, and B.
