What is the code to install BiocManager package?

Question

I needed to install Rgraphgviz package, for which i found this code

if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")
BiocManager::install("Rgraphviz", version = "3.8")

It seems I need to install BiocManager package as well. Can anyone help me with this? or is there an other way?

Answer 1

If statement is checking if you already have BiocManager package installed, if not then install it. Because we will need this package to install other bioconductor packages.

BiocManager - A convenient tool to install and update Bioconductor packages.
