SMACOF MDS (Metric or Non-metric)

Performs MDS using SMACOF algorithm from the smacof package

Usage

tidy_mds_smacof(dist_mat, ndim = 2, type = "ratio", ...)

Arguments

dist_mat

A distance matrix (dist object)

ndim

Number of dimensions (default: 2)

type

Character; "ratio" for metric, "ordinal" for non-metric (default: "ratio")

...

Additional arguments passed to smacof::mds()

Value

A list of class "tidy_mds" containing:

• config: tibble of MDS coordinates

• stress: stress value from the SMACOF algorithm

• method: character string describing the MDS type

• model: the mds result

Examples

# \donttest{
d <- dist(USArrests)
mds <- tidy_mds_smacof(d, type = "ratio")
# }
