## Product metric

### Description

Returns the p-product metric of two metric spaces. Works for output of 'rdist', 'pdist' or 'cdist'.

### Usage

    product_metric(..., p = 2)

### Arguments

`...` | Distance matrices or dist objects
`p` | The power of the Minkowski distance

### Examples

    # generate data
    df <- matrix(runif(200), ncol = 2)
    # distance matrices
    dist_mat <- pdist(df)
    dist_1 <- pdist(df[, 1])
    dist_2 <- pdist(df[, 2])
    # product distance matrix
    dist_prod <- product_metric(dist_1, dist_2)
    # check equality
    all.equal(dist_mat, dist_prod)
