concov | R Documentation |
Produces a table of combined species constancy and importance
concov(comm,clustering,digits=1,width=5,typical=TRUE,thresh=10)
comm |
a community data.frame, samples as rows and species as columns |
clustering |
(1) an object of class ‘clustering’, class ‘partana’, or class ‘partition’, (2) a vector of integer cluster memberships, (3) a factor vector, or (4) a character vector |
digits |
the number of digits for the importance value of species |
width |
controls the formatting of columns |
typical |
an argument passed to |
thresh |
a threshold parameter to control the suppression of small details in the output. Species must have >= thresh constancy in at least one type to appear in the output table |
concov calls const
and
importance
and then combines the output in a single table.
a data.frame with factors (combined constancy and coverage) as columns
Constancy-coverage tables are an informative and concise representation of species in classified types. The output format [constancy(mean cover)] follows the convention of the US Forest Service vegetation classifications.
