BiocLite to install packages

As example to install packages we will use the BSgenome package. This is a data package which contains representations of several genomes. When you install a new package it usually calls installations for its dependencies that takes some time, hence we have already installed BSgenome for you to use on this exercise.

Note: Using Bioconductor version 3.7 or earlier, packages can be installed using the following code:

# Using Bioconductor version 3.6
source("https://bioconductor.org/biocLite.R")
biocLite("BSgenome")

# Load the package
library(BSgenome)

For versions 3.8 or higher, you will use the BiocManager instead.

For this exercise, you should not use source() or biocLite() to install BSgenome. This has already been done for you.

You can load the package using library(packageName) and check the package's version using the function packageVersion("packageName").

Use library() to load the package BSgenome. Note that BSgenome has already been installed for you.
Read the output messages and view the required packages.
Check the installed version of BSgenome.
