#' An R API to the Oxford COVID-19 Database
#'
#' The [OxCOVID19 Project](https://covid19.eng.ox.ac.uk) aims to increase
#' our understanding of the COVID-19 pandemic and elaborate possible strategies
#' to reduce the impact on the society through the combined power of statistical,
#' mathematical modelling, and machine learning techniques. **The OxCOVID19**
#' **Database** is a large, single-centre, multimodal relational database
#' consisting of information (using acknowledged sources) related to COVID-19
#' pandemic. This package provides an R-specific interface to the
#' **OxCOVID19 Database** based on widely-used data handling and manipulation
#' approaches in R.
