cmdscale function

Wrapper to cmdscale for S3 class

cmdscale(d, k = 2, eig = FALSE, ...)

Arguments

• d: a distance structure such as that returned by 'dist' or a full symmetric matrix containing the dissimilarities
• k: the maximum dimension of the space which the data are to be represented in
• eig: indicates whether eigenvalues should be returned. Defaults to TRUE.
• ...: additional parameters passed to cmdscale. See cmdscale

Returns

Object of class 'cmdscalex' and 'cmdscale' extending cmdscale. This wrapper always returns the results of cmdscale as a list, adds column labels to the $points and adds extra elements (conf=points, delta=d, confdist=dist(conf), dhat=d) and the call to the list, and assigns S3 class 'cmdscalex' and 'cmdscale'.

Details

overloads stats::cmdscale turns on the liosting and adds slots and class attributes for which there are methods.

Examples

dis<-as.matrix(smacof::kinshipdelta)
res<-cmdscale(dis)
