In rPDBapi: A Comprehensive Interface for Accessing the Protein Data Bank

Batch Fetch RCSB PDB Data with Optional Retry and Cache

Description

This additive helper retrieves data in batches and can retry failed batches. Caching is optional and disabled by default, preserving existing package behavior.

Usage

data_fetcher_batch(
  id,
  data_type = "ENTRY",
  properties,
  return_as_dataframe = TRUE,
  batch_size = 50,
  retry_attempts = 3,
  retry_backoff = 0.5,
  progress = FALSE,
  cache = FALSE,
  cache_dir = NULL,
  verbosity = FALSE
)

Arguments

id	Character vector of identifiers.
data_type	Data type passed to data_fetcher().
properties	Property list passed to data_fetcher().
return_as_dataframe	Logical; passed through to data_fetcher().
batch_size	Number of IDs per batch.
retry_attempts	Number of retry attempts per batch.
retry_backoff	Backoff multiplier in seconds.
progress	Logical; show progress messages when TRUE.
cache	Logical; enable on-disk cache.
cache_dir	Optional cache directory.
