plotWL: Plot of the weight-length relationship by sex

In nwfsc-assess/PacFIN.Utilities: Generate fishery composition data from PacFIN data for the NWFSC

Plot of the weight–length relationship by sex

Description

Plot the weight–length relationship using ggplot2::ggplot. Sex-specific relationships are plotted if available using shades of gray. Note that sex can be missing and a single relationship for all data will be plotted.

Usage

plotWL(
  length,
  sex,
  weight,
  weight.calc,
  xlab = "Length (cm)",
  ylab = "Weight (kg)"
)

Arguments

length	A vector of fish lengths in mm.
sex	A vector of sexes for each entry in length. Entries must be one of the following: 'U', 'F', 'M', or 'H'.
weight	A vector of empirical weights in kilograms.
weight.calc	A vector of estimated weights output from getweight.
xlab, ylab	A character value specifying the label for an axes of a figure. This is typically passed to ggplot2::xlab or ggplot2::ylab but it can also be passed to the xlab or ylab arguments of plot. No additional formatting will take place.
