Show two size spectra in the same plot

Usage

plotSpectra2(
  object1,
  object2,
  name1 = "First",
  name2 = "Second",
  power = 1,
  ...
)

object1: First MizerParams or MizerSim object.
object2: Second MizerParams or MizerSim object.
name1: An optional string with the name for the first model, to be used in the legend. Set to "First" by default.
name2: An optional string with the name for the second model, to be used in the legend. Set to "Second" by default.
power: The abundance is plotted as the number density times the weight raised to this power. The default power = 1 gives the biomass density, whereas power = 2 gives the biomass density with respect to logarithmic size bins.
...: Parameters to pass to plotSpectra()

A ggplot2 object

sim1 <- project(NS_params, t_max = 10)
sim2 <- project(NS_params, effort = 0.5, t_max = 10)
plotSpectra2(sim1, sim2, "Original", "Effort = 0.5")
