[R] How to remove double loop?

Bill, Alberto, Gabor, Thank you for answering my question. Now I learned about outer() function. That was a straightforward example. But what if I had a matrix, where the last column was filled with values first (again, a for loop), and the rest was filled by using a double loop? OVal -

Re: [R] How to remove double loop?

Read the posting guide (the bit about reproducible code): OVal - matrix(0, n+1, n+1) for(i in 0:n){ + OVal[i+1, n+1] - max(Val[i+1, n+1]-K, 0) + } Error: object Val not found for(i in seq(n,1, by=-1)){ + for(j in 0:(i-1)){ + OVal[j+1, i] - a*((1-p)*OVal[j+1, i+1]+p*OVal[j+2,
