Plot mizer arrays

Many mizer functions return values that depend on species and either size or time. plot() creates a ggplot2 figure with one line for each species showing the values against size or against time (depending on the type of output). plotHover() creates an interactive version of the same figure.

Details

This works because the mizer functions that give values that depend on species and size return an ArraySpeciesBySize object and those that give values that depend on species and time return an ArrayTimeBySpecies object. These objects have attributes that store the name of the value, its units, and a reference to the MizerParams object that the value was computed from. This allows the plots to be automatically labelled and coloured appropriately.

To compare two mizer arrays in a single plot, use plot2(). To show the relative difference between two arrays, use plotRelative().

All methods return a ggplot2 object, unless return_data = TRUE, in which case they return the underlying data frame instead. plotHover() returns a plotly object.

Arguments used by all methods:

species: Character vector of species to include. NULL (default) means all species.
highlight: Name or vector of names of the species to be highlighted.
total: A boolean value that determines whether the total over all selected species is plotted as well. Default is FALSE.
background: A boolean value that determines whether background species are included. Ignored if the model does not contain background species. Default is TRUE.
return_data: If TRUE, return the data frame instead of the plot.
log_x: If TRUE, use a log10 x-axis. The default depends on the method; see its own help page.
log_y: If TRUE, use a log10 y-axis. The default depends on the method; see its own help page.
log: Character string specifying which axes should use log10 scales, in the same form as the base plot() argument. For example, "x", "y", "xy" or "". If supplied, this overrides log_x and log_y.
ylim: A numeric vector of length two providing lower and upper limits for the value (y) axis. Use NA to refer to the existing minimum or maximum.
y_ticks: The approximate number of ticks desired on the y axis.

Additional arguments for plot.ArraySpeciesBySize() and plot.ArrayTimeBySpeciesBySize():

all.sizes: If FALSE (default), values outside a species' size range (w_min to w_max) are removed.
wlim: A numeric vector of length two providing lower and upper limits for the weight (x) axis. Use NA to refer to the existing minimum or maximum.
llim: A numeric vector of length two providing lower and upper limits for the length (x) axis when size_axis = "l". Use NA to refer to the existing minimum or maximum.
size_axis: Whether to plot size as weight ("w", default) or length ("l"), using the allometric weight-length relationship.

Additional argument for plot.ArrayTimeBySpecies():

tlim: A numeric vector of length two providing lower and upper limits for the time axis, e.g. c(1980, 2000). Use NA to apply no limit at that end. Default is c(NA, NA).

Additional argument for plot.ArrayTimeBySpeciesBySize() and plot.ArrayTimeByResourceBySize():

time: The time to display. Default (NULL) is the final time step.

See the individual method help pages for each method's exact arguments and defaults: plot.ArraySpeciesBySize(), plot.ArrayTimeBySpecies(), plot.ArrayTimeBySpeciesBySize(), plot.ArrayResourceBySize(), plot.ArrayTimeByResourceBySize().

Examples

# \donttest{
plot(getEncounter(NS_params))

plot(getFeedingLevel(NS_params), species = c("Cod", "Herring"))

plot(getPredMort(NS_params), species = c("Cod", "Herring"),
     size_axis = "l")

plot(getBiomass(NS_sim))

plot(getBiomass(NS_sim), species = c("Cod", "Herring"), total = TRUE)

plot(getYield(NS_sim), species = c("Cod", "Herring"))

plot(getFMort(NS_sim), time = 2010)

plot(getResourceMort(NS_params))

plot(initialNResource(NS_params))
#> Warning: log-10 transformation introduced infinite values.

plot(NResource(NS_sim))
#> Warning: log-10 transformation introduced infinite values.
