Defaults.Mclust {mclust} | R Documentation |
A named list of values including an enumeration of models used as defaults in MCLUST functions.
A function mclustOptions
is supplied for assigning values to
the .Mclust
list.
A list with the following components:
emModelNames |
A vector of character strings associated with multivariate models for
which EM estimation is available in MCLUST. The current default is the following list: "EII": spherical, equal volume "VII": spherical, unequal volume "EEI": diagonal, equal volume and shape "VEI": diagonal, varying volume, equal shape "EVI": diagonal, equal volume, varying shape "VVI": diagonal, varying volume and shape "EEE": ellipsoidal, equal volume, shape, and orientation "EEV": ellipsoidal, equal volume and equal shape "VEV": ellipsoidal, equal shape "VVV": ellipsoidal, varying volume, shape, and orientation |
hcModelNames |
A vector of character strings associated with multivariate models for
which model-based hierarchical clustering is available in MCLUST. The current default is the following list: "EII": spherical, equal volume "VII": spherical, unequal volume "EEE": ellipsoidal, equal volume, shape, and orientation "VVV": ellipsoidal, varying volume, shape, and orientation |
bicPlotSymbols |
A vector whose entries correspond to graphics symbols for plotting the
BIC values output from Mclust and mclustBIC .
These are displayed in the legend which appears at the lower right
of the BIC plots.
|
bicPlotColors |
A vector whose entries correspond to colors for plotting the
BIC curves from output from Mclust and mclustBIC .
These are displayed in the legend which appears at the lower right
of the BIC plots.
|
classPlotSymbols |
A vector whose entries are either integers corresponding to graphics symbols or single characters for indicating classifications when plotting data. Classes are assigned symbols in the given order. |
classPlotColors |
A vector whose entries correspond to colors for indicating classifications when plotting data. Classes are assigned colors in the given order. |
warn |
A logical value indicating whether or not to issue certain warnings
(usually involving singularity). Default: warn = TRUE .
