rfishbase (version 3.1.5)

popchar: popchar

Description

Table of maximum length (Lmax), weight (Wmax) and age (tmax)

Usage

popchar(
  species_list = NULL,
  fields = NULL,
  server = getOption("FISHBASE_API", "fishbase"),
  version = get_latest_release(),
  db = default_db(),
  ...
)

Arguments

species_list

A vector of scientific names (each element as "genus species"). If empty, a table for all fish will be returned.

fields

a character vector specifying which fields (columns) should be returned. By default, all available columns recognized by the parser are returned. Mostly for backwards compatibility as users can subset by column later

server

can be set to either "fishbase" or "sealifebase" to switch between databases. NOTE: it is usually easier to leave this as NULL and set the source instead using the environmental variable `FISHBASE_API`, e.g. `Sys.setenv(FISHBASE_API="sealifebase")`.

version

a version string for the database, will default to the latest release. see [get_releases()] for details.

db

the

...

unused; for backwards compatibility only

Details

See references for official documentation. From FishBase.org: This table presents information on maximum length (Lmax), weight (Wmax) and age (tmax) from various localities where a species occurs. The largest values from this table are also entered in the SPECIES table. The POPCHAR table also indicates whether the Lmax, Wmax and tmax values or various combinations thereof refer to the same individual fish.
