In AgePopDenom: Model Fine-Scale Age-Structured Population Data using Open-Source Data

Generate and Save Raster Plot for Gamma Predictions

Description

This function creates rasters from prediction data, combines them into a stack, and saves the faceted plot to a specified file.

Usage

generate_gamma_raster_plot(
  predictor_data,
  pred_list,
  country_code,
  output_dir,
  save_raster = TRUE,
  file_name_suffix = "gamma_prediction_rasters",
  width = 2500,
  height = 2000,
  png_resolution = 300
)

Arguments

predictor_data	A data frame containing 'web_x' and 'web_y' coordinates and associated prediction values.
pred_list	A list containing predictions ('shape_hat', 'scale_hat', 'mean_age_pred') for creating rasters.
country_code	A string representing the lowercase country code, used for naming the output file.
output_dir	A string specifying the directory where the plot should be saved.
save_raster	A logical input specifying whether to save output or not. Default is TRUE.
file_name_suffix	A string specifying the suffix for the file name (default is "gamma_prediction_rasters").
width	Numeric. Width of output plot in pixels (default: 2500).
height	Numeric. Height of output plot in pixels (default: 2000).
png_resolution	An integer specifying the resolution of the plot in DPI (default: 300).

Value

The path to the saved raster plot.

Examples

predictor_data <- data.frame(
  web_x = runif(100, -100, 100),
  web_y = runif(100, -50, 50)
)

pred_list <- list(
  shape_hat = rnorm(100, mean = 2, sd = 0.5),
  scale_hat = rnorm(100, mean = 10, sd = 2),
  mean_age_pred = rnorm(100, mean = 30, sd = 5)
)

generate_gamma_raster_plot(predictor_data,
                           pred_list,
                           country_code = "COD",
                           output_dir = file.path(tempdir()))
