EpiGraphDB is an analytical platform and database to support data mining in epidemiology. The platform incorporates a graph of causal estimates generated by systematically applying Mendelian randomization to a wide array of phenotypes, and augments this with a wealth of additional data from other bioinformatic sources. EpiGraphDB aims to support appropriate application and interpretation of causal inference in systematic automated analyses of many phenotypes.
epigraphdb is an R package to provide ease of access to EpiGraphDB services. We will refer to epigraphdb as the name of the R package whereas "EpiGraphDB" as the overall platform.
To install the latest development version from github (
devtools is required
):
# install.packages("devtools")
devtools::install_github("MRCIEU/epigraphdb-r")To install a stable version from CRAN:
install.packages("epigraphdb")NOTE: while the package repository is "epigraphdb-r", the R package name is "epigraphdb".
epigraphdb provides a simple and intuitive way to query the API, as:

how to use the API in R please check out the following articles:
Users can use the general query function query_epigraphdb to get data from an API endpoint on EpiGraphDB without having to deal with HTTP requests by themselves. We also provide a list of functions (see the table below) that are equivalent to the upstream endpoints for the ease of use.
If you would like to contribute to this package, please check out documentation on setting up development and currently planned updates.
