Alternative R Code for Nested Comparison using sapply
The code provided uses a nested sapply approach to achieve the same result as the original double-for loop. Here is the equivalent code: outer(splt, splt, function(y, z) sum(y >= max(z)) / length(y), na.rm = TRUE) This will produce the same results as the original output. However, if you want to stick with a sapply approach but avoid using setNames, you can use the following code: outer(splt, splt, function(x, y) { sum(x >= max(y)) / length(x) }, na.
