makeKNNgraph {dimRed} R Documentation

## makeKNNgraph

### Description

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

### Usage

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


### Arguments

 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.

### Value

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