Installing
Bioconductor
Step 1: Install
BiocManager
BiocManager is the package manager for Bioconductor. It replaces the
older biocLite()
function.
# Check if BiocManager is already installed
if (!require("BiocManager", quietly = TRUE))
install.packages("BiocManager")
# Load BiocManager
library(BiocManager)
Step 2: Verify
Installation
# Check BiocManager version
BiocManager::version()
# Check if installation is valid
BiocManager::valid()
Step 3: Install
Core Bioconductor Packages
# Install core Bioconductor packages
BiocManager::install()
# This installs the core set of Bioconductor packages
# Including: BiocGenerics, S4Vectors, IRanges, GenomeInfoDb, etc.
Using BiocManager
Installing Specific
Packages
# Install a single package
BiocManager::install("DESeq2")
# Install multiple packages
BiocManager::install(c("edgeR", "limma", "GenomicRanges"))
# Install with dependencies
BiocManager::install("ComplexHeatmap", dependencies = TRUE)
Installing from
Different Sources
# Install from Bioconductor
BiocManager::install("Biostrings")
# Install from CRAN (BiocManager can handle this too)
BiocManager::install("ggplot2")
# Install from GitHub
BiocManager::install("jokergoo/ComplexHeatmap") # username/repository
# Example: Installing a development version from GitHub
BiocManager::install("Bioconductor/BiocGenerics")
Checking Available
Packages
# List all available Bioconductor packages
available_packages <- BiocManager::available()
head(available_packages, 20)
# Search for specific packages
grep("RNA", available_packages, value = TRUE)[1:10]
# Check if a package is available
"DESeq2" %in% available_packages
Upgrading and
Maintaining Bioconductor
Updating
Packages
Update All
Packages
# Update all installed packages
BiocManager::install(update = TRUE, ask = FALSE)
# Interactive update (will prompt for each package)
BiocManager::install(update = TRUE, ask = TRUE)
Update Specific
Packages
# Update specific packages only
BiocManager::install(c("DESeq2", "edgeR"), update = TRUE)
# Force reinstallation
BiocManager::install("limma", force = TRUE)
Upgrading
Bioconductor Version
# Check current Bioconductor version
BiocManager::version()
# Upgrade to the latest Bioconductor release
# This will upgrade R packages to match the new Bioconductor version
BiocManager::install(version = "3.18") # Specify version number
Managing Package
Versions
# Install a specific version of a package
BiocManager::install("DESeq2", version = "1.38.0")
# Check compatibility
BiocManager::valid()
# Fix invalid installations
BiocManager::valid(fix = TRUE)
