Details

This chewie_unset_cache function will remove the CHEWIE_PARQUET_CACHE environment variable from the .Renviron file.

chewie_clear_find_cache deletes the cached .rds files in the GEDI find cache directory, located in getOption("chewie.find.gedi.cache").

chewie_clear_h5_temp_cache deletes the cached .h5 files in the GEDI h5 - these files sometimes persist when a download in incomplete or there has been an error with the download. If you are having trouble downloading data, running this command could well help.

chewie_clear_parquet_cache deletes the cached .parquet files in the GEDI parquet cache directory, located in getOption("chewie.parquet.cache").

This function should almost never be used. Situations where this may be useful might include - requiring to free up disk space, if you are experiencing issues with the cache, or if there are package updates which render the existing cache irrelevant or incompatible.
