Convert a dist or matrix object into a Dissimilarity object

Create a Dissimilarity matrix from an existing distance matrix as dist object (e.g., from stats::dist(), or vegan::vegdist()), or from a similarly shaped matrixobject.

as.dissimilarity(x, ...)

as_dissimilarity(x, ...)

# S3 method for class 'matrix'
as.dissimilarity(x, ...)

# S3 method for class 'dist'
as.dissimilarity(x, ...)

# S3 method for class 'Dissimilarity'
as.dissimilarity(x, ...)

Arguments

x

An object to coerce into a Dissimilarity object.

...

Further argument passed to the coercion method.

Value

A Dissimilarity object.
