Plot population trends — plot.narwproj • narwind

Takes one or more narwproj object(s) and creates plots of the estimated population trajectories.

# S3 method for narwproj
plot(
  ...,
  interval = TRUE,
  cohort = FALSE,
  noaa = FALSE,
  scales = "free",
  ncol = 3,
  nx = 5,
  ny = 5
)

Arguments

...: One or more objects of class narwproj, as returned by predict.narwsim.
interval: Logical. If TRUE, percentile confidence intervals are shown on the plots. Defaults to TRUE.
cohort: Logical. If TRUE, separate plots are returned for each cohort. If FALSE, a single plot for the whole population is shown. Defaults to FALSE.
noaa: Logical. If TRUE, the population trajectory predicted as part of NOAA's population viability analysis (Runge et al., 2023) is also plotted. Defaults to FALSE.
scales: Character. Defines whether axis scales should be constant or vary across plots. Can be one of "fixed" or "free" (the default).
ncol: Integer. Number of columns for the plot layout when cohort = TRUE. Defaults to 3.
nx: Integer. Desired number of x-axis intervals. Non-integer values are rounded down. Defaults to 5. See pretty for details.
ny: Integer. Desired number of y-axis intervals. Non-integer values are rounded down. Defaults to 5. See pretty for details.
