summary.cma: Summarising the extraction of close modern analogues

Description

summary method for class "cma".

Usage

## S3 method for class 'cma':
summary(object, \dots)

Arguments

object

an object of class "cma", usually the result of a call to cma.

...

arguments passed to or from other methods.

Value

• An object of class "summary.cma" with the components below. The cut off threshold used to define close modern analogues and the dissimilarity coefficient used are returned as attributes "cutoff" and "method" respectively.
• distances
  a matrix of distances/dissimilarities. Individual columns contain the ordered close modern analogues for individual fossil samples. Rows of this matrix refer to the $k^{\mathrm{th}}$ closest analogue for each fossil sample. See notes below.
• samples
  a matrix of sample names from the reference set that are close modern analogues for a fossil sample. Individual columns contain the ordered close modern analogues for individual fossil samples. Rows of this matrix refer to the $k^{\mathrm{th}}$ closest analogue for each fossil sample. See notes below.
