Extracts covariates from Observational Medical
    Outcomes Partnership (OMOP) Common Data Model (CDM) domains using an
    R-only pipeline. Supports configurable temporal windows,
    domain-specific covariates for drug exposure, drug era (including
    Anatomical Therapeutic Chemical (ATC) groupings), condition
    occurrence, condition era, concept sets and cohorts. Methods are
    based on the Observational Health Data Sciences and Informatics
    (OHDSI) framework described in Hripcsak et al. (2015)
    <doi:10.1038/sdata.2015.35> and "The Book of OHDSI"
    OHDSI (2019, ISBN:978-1-7923-0589-8).

Provides cohort pathway analysis for Observational Medical
    Outcomes Partnership (OMOP) Common Data Model databases,
    including both standard (post-index) and pre-index pathway analyses.
    The pre-index analysis identifies sequences of events occurring in a
    lookback window before the target cohort index date. Built on the
    'CohortPathways' analysis framework originally developed by Christopher
    Knoll and the Observational Health Data Sciences and Informatics
    community through 'WebAPI'. Methodological background and the
    originating implementation are described in
    <https://github.com/OHDSI/CohortPathways>.

Tools to build single-event survival datasets from "OMOP CDM"
    cohorts and estimate survival outcomes. The package supports Kaplan-Meier,
    Cox proportional hazards, and parametric accelerated-failure-time models,
    with optional stratification by gender and age groups.

An interface to the search API of 'HAL'
    <https://hal.science/>, the French open archive for scholarly
    documents from all academic fields. This package provides programmatic
    access to the API <https://api.archives-ouvertes.fr/docs> and allows
    to search for records and download documents.

Search and extract data from the Organization for Economic 
    Cooperation and Development (OECD).

Access and Analyze Official Development Assistance (ODA) data using 
    the OECD API <https://gitlab.algobank.oecd.org/public-documentation/dotstat-migration/-/raw/main/OECD_Data_API_documentation.pdf>.
    ODA data includes sovereign-level aid data such as key aggregates (DAC1), geographical
    distributions (DAC2A), project-level data (CRS), and multilateral contributions (Multisystem).
