matrix with the same dimensions as the original data matrix, but with factors coded as 0 and 1, and all missing values replaced.

a vector giving a permutation of the original observations to allow for plotting, in the sense that the branches of a clustering tree will not cross.

a vector similar to order, but containing observation labels instead of observation numbers. This component is only available if the original observations were labelled.

vector of length n-1 where n is the number of observations, specifying the variables used to separate the observations of order.

vector of length n-1 where n is the number of observations, specifying the separation steps at which the observations of order are separated.
