emModelNames

A vector of 3-character strings that are associated with multivariate
models for which EM estimation is available in MCLUST.
The current default is all of the multivariate mixture models
supported in

`MCLUST`

.
The help file for <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

bicPlotSymbols

A vector whose entries are either integers corresponding to graphics
symbols or single characters for plotting BIC curves.
The default is

`c(EII=17,VII=2,EEI=16,EVI=10,VEI=13,VVI=1,`

`EEE=15,EEV=12,VEV=7,VVV=0,E=17,V=2)`

.bicPlotColors

A vector whose entries are either integers corresponding to colors
to BIC curves.

`c(EII="gray",VII="black",`

`EEI="orange",EVI="brown",VEI="red",VVI="magenta",`

`EEE="forestgreen",EEV="green",VEV="cyan",VVV="blue",`

classPlotSymbols

A vector whose entries are either integers corresponding to graphics
symbols or single characters for plotting for
classifications. Classes are assigned symbols in the given order.
The default is

`c(17,0,10,4,11,18,6,7,3,16,2,12,8,15,1,9,`

classPlotColors

A vector whose entries are either integers corresponding to graphics
symbols or single characters for plotting for
classifications. Classes are assigned symbols in the given order.
The default is

`"blue", "red", "green", "cyan", "magenta`

warn

A logical value allowing some types of warnings to be turned on
or off globally. Most of these warnings have to do with
situations in which singularities are encountered.
The default is

`warn = TRUE`

.- A named list in which the names are the names of the arguments and the values are the values supplied to the arguments.

`mclustOptions`

is provided for assigning values
to the `.Mclust`

list, which is used
to supply default values to various functions in MCLUST.
Calls to `mclustOptions`

do not in themselves affect
the outcome of computations.`.Mclust`
