Look carefully at your output (and I don't think that you are showing
us the output of what you actually ran in the order that you ran it).
After running `x %=% 1` you should see that x has the value `1`, but
your output shows `2`, this is the result of the next command `y$a %=%
2`, see the `-`
outer() and dist() are good for speed on smaller problems but they
require O(length(X)^2) memory. This can slow things down or even
stop the calculations for large problems. You can gain a lot of speed
without the memory problem by summing things up in chunks.
