## Installation
### Bioconductor
The `ReactomeGSA` package is part of Bioconductor since version 3.10. You can find detailed information on the latest stable version on [ReactomeGSA's Bioconductor page](https://doi.org/doi:10.18129/B9.bioc.ReactomeGSA).
To install the latest version from Bioconductor use
```r
if (!requireNamespace("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install("ReactomeGSA")
```
### Latest Version
Bioconductor is updated every 6 months. You can still get the latest version of the ReactomeGSA package directly from GitHub:
```r
# install devtools if needed
if (!require(devtools)) {
install.packages("devtools")
}
# install the ReactomeGSA package
if (!require(ReactomeGSA)) {
install_github("reactome/ReactomeGSA")
}
```
