This method function extracts the correlation matrix, or list of
correlation matrices, associated with object
.
# S3 method for corStruct
as.matrix(x, …)
an object inheriting from class "corStruct"
,
representing a correlation structure.
further arguments passed from other methods.
If the correlation structure includes a grouping factor, the returned
value will be a list with components given by the correlation
