1	comparisons_to_matrix(n.areas, comparisons)

`n.areas`	The number of areas in the study.
`comparisons`	An N x 2 data frame, where N is the number of comparisons. Each row should correspond to a judgement. The first column is the better area, the second column is the more deprived area. The areas should be labeled from 1 to n.areas.

A matrix where the i, j^th element is the number of times area i beat area j.

#Generate some sample comparisons
comparisons <- data.frame("winner" = c(1, 3, 2, 2), "loser" = c(3, 1, 1, 3))

#Create matrix from comparisons
win.matrix <- comparisons_to_matrix(3, comparisons)
