convert_plot_size_axis: Convert plotting data from weight to length

Description

When size_axis = "l", adds a length column l computed from the weight column w using each species' weight-length relationship. For size_axis = "w" the data is returned unchanged.

Usage

convert_plot_size_axis(
  plot_dat,
  params,
  size_axis,
  species_col = "Species",
  drop_w = TRUE
)

Value

The plotting data, with a length column l added (and w optionally dropped) when size_axis = "l".

Arguments

plot_dat

A data frame of plotting data with a w column and a species column.

params

A MizerParams object providing the weight-length parameters.

size_axis

Either "w" (weight) or "l" (length).

species_col

Name of the column identifying the species. Default is "Species".

drop_w

If TRUE (default), the w column is dropped once l has been computed.
