Summarise the extraction of close modern analogues
Description
summary
method for class "cma"
.
Usage
## S3 method for class 'cma'
summary(object, ...)
Arguments
object |
an object of class |
... |
arguments passed to or from other methods. |
Value
An object of class "summary.cma"
with the components of an
object of class cma
, plus:
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
|
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
|
Note
Currently, only objects of class analog
are supported.
The number of rows in the returned matrices is equal to the maximum
number of close modern analogues identified for an individual fossil
sample. If no close modern analogues exist for an individual fossil
sample are identified, then the relevant column in "distances"
will contain all missing values and in "samples"
the string
"none"
. Rows of individual columns will be padded with missing
values if the number of close modern analogues for that sample is less
than the maximum number of close modern analogues identified for a
single sample.
