[R] calculating an N50

Given a set of integers of different values how do I calculate the minimum number of the largest of integers that are required, when summed, to equal 50% of the total sum of the the set? For example, > length(myTable$lgth) [1] 303403 > sum(myTable$lgth) [1] 4735396 I know through brute force that
