biodbChebi

An R Bioconductor package for accessing ChEBIonline database, based on Bioconductor package/frameworkbiodb.

Introduction

biodbChebi is an extension package of the biodb package. It allows to connect to ChEBI for retrieving entries, searching for entries by name or mass, and convert CAS IDs or InChI to ChEBI IDs.

Examples

Getting a single entry:

bdb <- biodb::newInst() chebi <- bdb$getFactory()$createConn('chebi') entries <- chebi$getEntry(c('2528', '7799', '15440')) bdb$entriesToDataframe(entries)

Searching by name and mass:

bdb <- biodb::newInst() chebi <- bdb$getFactory()$createConn('chebi') ids <- chebi$searchCompound(name='aspartic', mass=133, mass.field='molecular.mass', mass.tol=0.3, max.results=3)

See the vignette for more examples.

Installation

Install the latest stable version using Bioconductor:

if (!requireNamespace("BiocManager", quietly = TRUE)) install.packages("BiocManager") BiocManager::install('biodbChebi')
