Description Usage Arguments Value
A metric multidimensional scaling algorithm that minimizes a least squares loss function based on the dissimilarities Heiser \& De Leeuw, 80 and 77; Gutman 68). The lettters in SMACOF stand for Scaling by MAjorizing a COmplicated Function.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
D |
dissimilarities/distances of class dist. |
niter |
max number of iterations to use, default is set to 20: 'to iterate is heaven, to converge is divine'. Convergence does not necessarily give you the best non-linear mapping of the dissimilarity structure. |
interc |
logical for including an additive constant in the smacof algorithm. |
inicon |
intial configuration. By default this is specified as NULL, here the SMACOF algorithm specifies... |
groupnr |
groupnr when known, each object can be given a number to which group it belongs |
colv |
vector containing color names for each group number |
main |
title of the plot, by default there is no title. |
k |
number of dimensions |
pch |
plotting 'character', i.e. symbol to use. This can either be a single character or an integer code for one of a set of graphics symbols. The full set of S symbols is available with |
PLOT |
whether to plot or not to plot, by default TRUE. |
VERBOSE |
whether to give a stdout on the criterion for each iteration, by default set to equal TRUE. |
... |
arguments which can be parsed to either the |
