An implementation of DuMouchel's (1999) <doi:10.1080/00031305.1999.10474456>
  Bayesian data mining method for the market basket problem.
  Calculates Empirical Bayes Geometric Mean (EBGM) and posterior quantile scores
  using the Gamma-Poisson Shrinker (GPS) model to find unusually large cell
  counts in large, sparse contingency tables. Can be used to find unusually high
  reporting rates of adverse events associated with products. In general, can be
  used to mine any database where the co-occurrence of two variables or items is
  of interest. Also calculates relative and proportional reporting ratios.
  Builds on the work of the 'PhViD' package, from which much of the code is
  derived. Some of the added features include stratification to adjust for
  confounding variables and data squashing to improve computational efficiency.
  Includes an implementation of the EM algorithm for hyperparameter estimation
  loosely derived from the 'mederrRank' package.

Access data and processing functionalities of 'openEO' compliant back-ends in R.

The 'openFDA' API facilitates access to Federal Drug Agency (FDA)
  data on drugs, devices, foodstuffs, tobacco, and more with 'httr2'. This
  package makes the API easily accessible, returning objects which the user can
  convert to JSON data and parse. Kass-Hout TA, Xu Z, Mohebbi M et al. (2016)

Social media sites often embed cards when links are shared, based on
    metadata in the 'Open Graph Protocol' (<https://ogp.me/>). This supports extracting
    that metadata from a website. It further allows for the creation of tags to
    add to a website to support the 'Open Graph Protocol' and provides a list of the
    standard tags and their required properties.

The comprehensive knowledge of epigenetic modifications in plants, encompassing histone modifications in regulating gene expression, is not completely ingrained. It is noteworthy that histone deacetylation and histone H3 lysine 27 trimethylation (H3K27me3) play a role in repressing transcription in eukaryotes. In contrast, histone acetylation (H3K9ac) and H3K4me3 have been inevitably linked to the stimulation of gene expression, which significantly influences plant development and plays a role in plant responses to biotic and abiotic stresses. To our knowledge this the first multiclass classifier for predicting histone modification in plants. <doi:10.1186/s12864-019-5489-4>.
