Usage

smacofxDeleteOne(
  object,
  delta,
  weightmat,
  init,
  ndim,
  type,
  verbose = FALSE,
  itmaxi = 10000
)

Arguments

object	Object of class smacofP if used as method or another object inheriting from smacofB. Note we assume the MDS model was fitted on a symmetric matrix/data frame or dist object
delta	the data (symmetric matrix, data frame or dist object)
weightmat	weighting matrix
