##### Pairwise distances

Computes the matrix of distances between all pairs of points in a point pattern.

Keywords
spatial
##### Usage
pairdist(x, y=NULL, method="C")
##### Arguments
x,y
Arguments specifying the $x$ and $y$ coordinates of a set of points. Typically x and y would be numeric vectors of equal length. Alternatively y may be omitted and x may be a point patter
method
String specifying which method of calculation to use. Values are "C" and "interpreted".
##### Details

This function computes the Euclidean distances between all pairs of points, and returns the matrix of distances.

If method = "interpreted" then the distances are computed using interpreted R code only. If method="C" then C code is used. The C code is marginally faster.

##### Value

• A square matrix whose [i,j] entry is the distance between the points numbered i and j.
