plot_weight_length: Plots the weight-at-length data and estimates

In nwfsc-assess/nwfscSurvey: Northwest Fisheries Science Center Survey

Plots the weight-at-length data and estimates

Description

Plots the weight-at-length data and estimates

Usage

plot_weight_length(
  data,
  dir = NULL,
  estitmates = NULL,
  col_length = "length_cm",
  col_weight = "weight_kg",
  two_sex = TRUE,
  add_save_name = NULL,
  height = 7,
  width = 7,
  dpi = 300
)

Arguments

data	Data frame created by pull_bio()
dir	Directory where output will be saved. The directory where the file should be saved. If dir = NULL no output will be saved.
col_length	A numeric or character value specifying the column to use in data for length information. These lengths are assumed to be in centimeters. The default value is length_cm.
col_weight	A numeric or character value specifying the column to use in data for weight information. These weights are assumed to be in kilograms The default value is weight_kg. Using kilograms is the default because Stock Synthesis assumes the weight-length parameters are calculated using centimeters and kilograms. The reported values are easily scaled to give you results in grams if you wish to have more standard parameter estimates.
two_sex	Default TRUE. If TRUE the sexed data will be plotted and if FALSE all data will be plotted as unsexed. If estimates are passed to the function then the corresponding parameter estimates will be plotted.
add_save_name	Option to add text to a saved figure name. This option can be useful if creating plots across multiple species and saving them into a single folder. The default is NULL. Note that the biomass estimate, i.e., annual or strata, are already included in the saved name so no need to add those here.
width, height	Numeric values for the figure width and height in inches. The defaults are 7 by 7 inches.
dpi	The resolution to apply when saving figures. Lower resolution values can reduce file size which can be helpful when creating large documents with many figures. The default is 300.
estimates	Data frame of weight-at-length estimates from est_weight_length(). If passed to the function the estimated parameter values will be added to the plot. The default is NULL and will not add parameters to the plot.
