(50 pts) The term used in the Nature letter for what we call
"coordinates" is ________________________.

QUESTION -ext .R -run 'Rscript omsi_answer2.R'

(50 pts) Implement PageRank, inputting the adjacency matrix ((i,j)
element is 1 or 0, depending on whether page i links directly to page j.
The call form will be

findPi(adj,k)

where k is the desired matrix power; if k = 0, use eigen() instead of
calculating matrix powers.  The return vector is pi.

Note that in the eigenvector approach, the result must be a probability
vector, i.e. nonnegative elements summing to 1.0.  You may need to scale
the output of eigen().  Note too that Re(z) returns the real part of a
complex number, e.g. Re(2+3i) = 2.

findPi <- function(adj,k) {



}

print(findPi(rbind(c(0,1,0),c(1,0,1),c(1,0,0)),k=10))
print(findPi(rbind(c(0,1,0),c(1,0,1),c(1,0,0)),k=0))
