create_spp(filename = "filelist.spp", weight = 1, alpha = 1, bqp = 1,
  bqp_p = 1, cellrem = 0.25, spp_file_dir, recursive = FALSE,
  spp_file_pattern = ".+\\.(tif|img)$", override_path = NULL)

Arguments

filename

character string defining the name of the spp file created.

weight

numeric template value for weights.

alpha

bqp

bqp_p

cellrem

numeric template value for cellrem values.

spp_file_dir

character path or a vector of paths to target dir.

recursive

Logical defining whether files in spp_file_dir should be listed recursively.

spp_file_pattern

pattern used to match raster files.

override_path

character path used to override the dirpath in input raster file paths. In case recursive = TRUE, then there can be an arbitrary number of subdirectories and override path is used only up until the spp_file_dir. This way the correct subdirectory structure is retained.
