makeKNNgraph

Create a K-nearest neighbor graph from data x. Uses nn2 as a fast way to find the neares neighbors.

makeKNNgraph(x, k, eps = 0, diag = FALSE)

`x`	data, a matrix, observations in rows, dimensions in columns
`k`	the number of nearest neighbors.
`eps`	number, if `eps > 0` the KNN search is approximate, see `nn2`
`diag`	logical, if `TRUE` every edge of the returned graph will have an edge with weight `0` to itself.

an object of type igraph with edge weight being the distances.
