R: Random Samples and Permutations
Earlier I wrote a code in Matlab for this sort of lottery function, just to test if it was possible. However, I actually needed it in PHP so Ive just rewritten the code and it does seem to work, but as it involves a lot of looping I want to make sure Im doing it as efficiently as possible.

Otherwise x can be any R object for which length and subsetting by integers make sense: S3 or S4 methods for these operations will be dispatched as appropriate. For sample the default for size is the number of items inferred from the first argument, so that sample(x) generates a random permutation of the elements of x (or 1:x ).

I just generated 10 random lotto numbers from 1 to 39, now I want to check if these numbers match my winning ticket for example w<-c(2,8,19,23,25,32,37) so that if I have 3 matches in particular combination the prize is 10$ for 4 50$ for 5 100$ for 6 2000$ and for all 7 100000$.

You have now created a function called sum.of.squares which requires two arguments and returns the sum of the squares of these arguments. Since you ran the code through the console, the function is now available, like any of the other built-in functions within R. Running sum.of.squares(3,4) will …

A lottery ticket contains five unique numbers. A set of unique numbers does not contain repeated elements. The winning combination of this lottery is chosen by picking five unique numbers. Define a function matches(ticket, winners) that takes two lists and returns an integer that says how many numbers the two lists have in common.
