## Overview

The `BiocManager` package allows users to install and manage packages
from the *[Bioconductor](https://bioconductor.org)* project, including
CRAN packages that depend or import Bioconductor packages. Bioconductor
focuses on the statistical analysis and comprehension of high-throughput
genomic data.

Current *Bioconductor* packages are available on a ‘release’ version
intended for every-day use, and a ‘devel’ version where new features are
continually introduced. A new release version is created every six
months. Using the `BiocManager` package helps users accurately install
packages from the appropriate release.

- `available()` shows all packages associated with a search pattern
- `install()` installs and/or updates packages either CRAN or
  Bioconductor
- `repositories()` shows all package repository URL endpoints
- `valid()` checks and returns packages that are out-of-date or too new
- `version()` returns the current Bioconductor version number

## Installation

``` r
if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager", repos = "https://cran.R-project.org")
```

## Usage

### Checking Bioconductor version currently in use

``` r
BiocManager::version()
#> [1] '3.21'
```

### Installing Bioconductor packages

``` r
BiocManager::install(c("GenomicRanges", "SummarizedExperiment"))
```

### Verifying a valid Bioconductor installation

``` r
BiocManager::valid()
#> [1] TRUE
```

detailed information such as changing Bioconductor version, offline use,
