mclust Analysis of a Spectra Object PCA Results
This function is a wrapper for the Mclust function and associated
plotting functions.
mclustSpectra(
spectra,
pca,
pcs = c(1:3),
dims = c(1, 2),
plot = c("BIC", "proj", "errors"),
use.sym = FALSE,
...
)spectra |
An object of S3 class |
pca |
An object of class |
pcs |
An integer vector describing which PCs to use. |
dims |
A integer vector giving the PCA dimensions to use. |
plot |
A character string indicating what plot to make. Options are
|
use.sym |
Logical; if true, the color scheme is changed to black and symbols are used for plotting. |
... |
Other parameters to be passed downstream. |
The Mclust model is returned invisibly, and a plot is made.
