Boolean with default
TRUE meaning to set the name of the $i$th element
to the species with abundance $i$ if unique. Set to
FALSE to suppress this, which is useful if the species names
are long
freq
Frequency data (eg as returned by phi())
string
Character; species name to prepend (using NULL
can be confusing)
Details
Function phi() coerces its argument to a count object and
by default returns a named vector whose $i$th element is the
number of species with $i$ individuals. The name of the
$i$th element is the species with abundance $i$ if unique
and empty otherwise. Function phi() is used by
theta.prob().
Function unphi() does the reverse: given the output of
phi(), it returns a corresponding count object. Note that
species names are lost.
