Principal coordinate analysis using the Jensen-Shannon divergence.
esov.mds(x, k = 2, eig = TRUE)
A matrix with the compositional data. Zero values are allowed.
The maximum dimension of the space which the data are to be represented in. This can be a number between
1 and
Should eigenvalues be returned? The default value is TRUE.
A list with the results of "cmdscale" function.
The function computes the Jensen-Shannon divergence matrix and then plugs it into the classical multidimensional scaling function in the "cmdscale" function.
