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

Estimate length-at-age using the von Bertanlaffy parametization from Stock Synthesis.

Description

Estimate length-at-age using the von Bertanlaffy parametization from Stock Synthesis.

Usage

est_growth(
  dir = NULL,
  dat,
  return_df = TRUE,
  Par = data.frame(K = 0.13, Linf = 55, L0 = 15, CV0 = 0.1, CV1 = 0.1),
  bySex = TRUE,
  estVB = TRUE,
  bins = NULL,
  sdFactor = 1,
  dopng = lifecycle::deprecated()
)

Arguments

dir	Directory to save output.
dat	The data loaded from the NWFSC database
return_df	TRUE/FALSE If set to TRUE the dat data frame is returned with added columns for the estimated Lhat_low, Lhat_pred, and Lhat_high.
Par	Dataframe of starting parameters for K, Linf, L0, CV0, and CV2 based on the Stock Synthesis parameterization of von Bertanlaffy growth.
bySex	Logical to indicate if plot by sex
estVB	Logical. Estimate vonB growth to plot against predicted length. If F, it uses the paramters in parStart.
bins	The bins to put ages into. If NULL then simply uses the ages as recorded.
sdFactor	The number of standard deviations to include in the low and high calculations. The default is 1.0.
dopng	Deprecated with nwfscSurvey 2.1 because providing a non-NULL value to dir can serve the same purpose as dopng = TRUE without the potential for errors when dopng = TRUE and dir = NULL. Thus, users no longer have to specify dopng to save the plot as a png.
