  outdir = NULL,
  verbose = TRUE
)

Arguments

data_paths

A list containing the data (either virtual raster files or local file folders) and output path for all types of SoilGrids texture data e.g. data_paths <- list( list( url = "/vsicurl?max_retry=30&retry_delay=60&list_dir=no&url=https://files.isric.org/soilgrids/latest/data/sand/sand_", local = NULL, save_path = paste0(outdir, "sand_percent.rds")), list( url = "/vsicurl?max_retry=30&retry_delay=60&list_dir=no&url=https://files.isric.org/soilgrids/latest/data/clay/clay_", local = NULL, save_path = paste0(outdir, "clay_percent.rds")), list( url = "/vsicurl?max_retry=30&retry_delay=60&list_dir=no&url=https://files.isric.org/soilgrids/latest/data/silt/silt_", local = NULL, save_path = paste0(outdir, "silt_percent.rds")))
