1. Installation

Let's begin by loading the wcfish package and its dependencies.

# Load package
library(wcfish)
library(tidyverse)

2. Datasets

The package includes the following West Coast fisheries datasets (listed below):

Coastwide datasets

• West Coast commercial fisheries species: ?taxa
• West Coast commercial fishing ports: ?ports
• West Coast commercial fishing blocks shapefile: ?blocks

California (CDFW) datasets

• Annual commercial landings by source and species: ?cdfw_waters
• Annual commercial landings by port and species: ?cdfw_ports
• Annual number of licensed commercial fishers by area of residence: ?cdfw_n_comm_fishers
• Annual number of registered commercial fishing vessels by length class: ?cdfw_n_comm_vessels_length
• Annual number of registered commercial fishing vessels by port complex: ?cdfw_n_comm_vessels_port
• Annual number of registered commercial fishing vessels: ?cdfw_n_comm_vessels
• Annual CPFV landings by port complex and species: ?cdfw_cpfv
• Annual CPFV participation and effort by port complex and species: ?cdfw_cpfv_effort
• Annual kelp harvest by bed type: ?cdfw_kelp
• Annual kelp harvest overall: ?cdfw_kelp_tots

PACFIN datasets

• Species meta-data: ?pacfin_species
• Ports and port complexes meta-data: ?pacfin_ports
• Annual commercial landings by state (CA/OR/WA), port complex, and species: ?pacfin_all6
• Monthly commercial Dungeness crab landings by state (CA/OR/WA) and port complex: ?pacfin_crab2

Other West Coast fisheries datasets

• Monthly commercial landings in CA by port complex and species from the SWFCC: ?swfsc
• Annual commercial landings in CA by port complex, gear type, and species from the CALCOM: ?calcom

3. Inspecting datasets

Every dataset is documented with metadata. To view the metadata for a dataset, use the ? command. For example, if you wanted to look at the meta-data for the cdfw_ports dataset, you would do the following:

# Examine the metadata for the cdfw_port dataset
?cdfw_ports

This will pop up a description of the dataset and its columns in the "Help" screen of your R text editor.

4. Saving the dataset as an object

You can save the dataset as an object in your R environment using the assingment operator:

# Save a dataset in your R environment
data <- wcfish::cdfw_ports

5. Preparing a quick plot of the dataset

We encourage you to work with the data and plot it based on your own needs. However, we also provide a plot_data function for generating a quick plot of the dataset of interest. Note that this only works for the CDFW datasets.

# Quickly plot a CDFW dataset
wcfish::plot_data("cdfw_ports")
