Write Response Curve PNGs for All Variables — maxent_plot_response

Generates response curve plots for each environmental variable and saves them as PNG files, replicating density/ResponsePlot.java::makeplot(). A full-size PNG and an optional thumbnail are written for every variable.

Usage

maxent_plot_response_curves(
  model,
  env_grids,
  feature_names,
  output_dir,
  species,
  var_indices = NULL,
  n_steps = 100L,
  thumbnail = TRUE,
  write_dat = FALSE
)

Arguments

model: External pointer to a trained FeaturedSpace object.
env_grids: List of external pointers to Grid<float> objects.
feature_names: Character vector of environment variable names (one entry per element of env_grids).
output_dir: Character: directory under which a plots/ sub-directory will be created.
species: Character: species name (used in file names).
var_indices: Integer vector of 0-based variable indices to plot. Defaults to all variables.
n_steps: Integer: number of steps in each curve (default 100).
thumbnail: Logical: also write a 210 × 140 pixel thumbnail PNG (default TRUE).
write_dat: Logical: also write a tab-delimited .dat file of the curve data (default FALSE).

Value

Invisibly returns a named list of file paths written.

Examples

if (FALSE) { # \dontrun{
maxent_plot_response_curves(
  model, list(g1, g2), c("bio1", "bio12"),
  output_dir = tempdir(), species = "Sp1")
} # }
