a data.frame with species as rows, classes as columns, with
average abundance of species in classes.
Arguments
comm
a data.frame of species abundances with samples as rows and
species as columns
clustering
a vector of (integer) class memberships, or an object of
class ‘clustering’, class ‘partana’,
of class partition
minval
the minimum importance a species must have in at least one class
to be included in the output
digits
the number of digits to report in the table
show
the minimum value a species must have to print a value
sort
a switch to control interactive re-ordering
typical
a switch to control how mean abundance is calculated.
Typical=TRUE divides the sum of species abundance by the number of plots in which
it occurs; typical=FALSE divides by the number of plots in the type
spcord
a vector of integers to specify the order in which species
should be listed in the table
dots
a switch to control substituting dots for small values
data(bryceveg) # returns a data.frame called brycevegdata(brycesite)
class <- cut(brycesite$elev,10,labels=FALSE)
importance(bryceveg,class,minval=0.25)
