rentrez

rentrez provides programmatic access to NCBI databases via the eUtils API, enabling search, download, and import of bibliographic, genetic, genomic, and medical records (e.g., PubMed, GenBank) into R for downstream analysis.

Key Features:

• NCBI eUtils API access: Interfaces with the NCBI eUtils API to query over 50 NCBI databases, including PubMed and GenBank.
• Data retrieval and import: Performs searching, downloading, and importing of records directly into R.
• Supported data types: Handles bibliographic, genetic, genomic, and medical records.
• Programmatic foundation: Provides a programmatic layer for building R packages that access and manipulate NCBI datasets.

Scientific Applications:

• Genomics: Retrieves sequence and genomic records from GenBank to support genomic analyses.
• Bibliometrics: Retrieves PubMed bibliographic records for literature mining and bibliometric studies.
• Data integration in R: Integrates NCBI datasets into R workflows for downstream statistical and bioinformatic analyses.
• Package development: Serves as a foundational data-access layer for development of specialized R packages.

Methodology:

Programmatically queries and retrieves data from NCBI via the eUtils API, downloading and importing records into R sessions.
