sep.species {CTFS} | R Documentation |
Provides access to a single or groups of dataframes in a
list where each dataframe is the tree records of a single
species. This list data file is generated with sep.data
. The
example data file is tst.bci90.spp
.
sep.species(spname, census.spp) load.species(spname, census.spp)
spname |
species names in quotes, either a single name or a vector of names |
census.spp |
the list structured dataset where each species is a
dataframe, eg. tst.bci90.spp |
These functions are similar to each other. load.species
only
works with one species name at a time and returns a data frame.
sep.species
returns a list that is a subset of data frames in census.spp
.
For sep.species
, if spname
is a single name then a data frame of tree records is
returned. If spname
is a vector of names, then a list of
data frames is returned, but only those data frames of the species names
in spname
.
For load.species
, spname
can only be a single value and a
data frame is always returned.
