as.matrix.corStruct.RdThis method function extracts the correlation matrix, or list of
correlation matrices, associated with object.
# S3 method for class '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
matrices for each group. Otherwise, the returned value will be a
matrix representing the correlation structure associated with
object.
