This package provides a set of tools for interacting with [FOBI
(Food-Biomarker
Ontology)](https://github.com/pcastellanoescuder/FoodBiomarkerOntology).
A collection of basic manipulation tools for biological significance
analysis, graph visualization and text mining strategies for annotating
nutritional data are provided here:
- Graph visualization of FOBI
- Parse FOBI information from OBO to a readable table format
- Compound ID conversion (among metabolite names, FOBI, ChemSpider,
KEGG, PubChemCID, InChIKey, InChICode and HMDB IDs)
- Biological significance analysis via ORA and MSEA methods:
- Chemical class enrichment analysis: ORA and MSEA using FOBI chemical
classes as metabolite sets
- Food enrichment analysis: ORA and MSEA using FOBI food groups as
metabolite sets
- Text mining algorithm for annotating free-text dietary data
`fobitools` also offers a Shiny app version called
[fobitoolsGUI](https://github.com/pcastellanoescuder/fobitoolsGUI). This
application implements most of `fobitools` functions in an user-friendly
web interface and it is available at
<http://webapps.nutrimetabolomics.com/fobitoolsGUI>.
# Installation
To install Bioconductor version use:
``` r
# install.packages("BiocManager")
BiocManager::install("fobitools")
```
If you need the GitHub version (not recommended unless you know what you
are doing), use:
``` r
# install.packages("devtools")
devtools::install_github("pcastellanoescuder/fobitools")
```
