a list with several data.frames: ‘vals’ with species name, mean similarity,
number of occurrences, and probability of observing as high a mean similarity as observed,
and ‘quantiles’ with the distribution of the quantiles of mean similarity for
given numbers of occurrences.
If drop=TRUE, results specific to dropping out each species in turn are added to the list
by species name.
Arguments
comm
a data frame of community samples, samples as rows, species as columns
dis
an object of class ‘dist’ from
dist,
dsvdis or
vegdist
numitr
the number of iterations to use to establish the quantiles
of the distribution
drop
a switch to determine whether to drop species out when calculating
their compspec value
progress
a switch to control printing out a progress bar
x
an object of class compspec
spc
an integer code to specify exactly which species drop-out to plot
