Distance Matrix Computation
This function computes the distances between the rows of a data matrix by using the specified distance measure.
This function returns a distance matrix by using dist
function.
The matrix dimension is (n1
x n1
) if
y=NULL
, (n1
x n2
) otherwise.
metric.dist(x, y = NULL, method = "euclidean", p = 2, dscale = 1, ...)
x |
Data frame 1. The dimension is ( |
y |
Data frame 2. The dimension is ( |
method |
The distance measure to be used. This must be one of "euclidean", "maximum", "manhattan", "canberra", "binary" or "minkowski". |
p |
The power of the Minkowski distance. |
dscale |
If scale is a numeric, the distance matrix is divided by the scale value. If scale is a function (as the mean for example) the distance matrix is divided by the corresponding value from the output of the function. |
