Please note that in this video, Saniya shows how to download Bioconductor in R (namely, how we download the BiocManager installer for Bioconductor packages in R). Saniya also goes over what CRAN is.
To install Bioconductor's BiocManager installer, we run this in R:
install.packages("BiocManager")
Then, we can download any Bioconductor packages (and additionally, any CRAN (Comprehensive R Archive Network) packages) using: BiocManager::install("packageName") where "packageName" is the name of the package we want to install.
To install multiple packages together, efficiently, we can do this: BiocManager::install(c("packageName1", "packageName2", "packageName3"))
That would help us download 3 package names together.
Please note that Bioconductor packages (https://bioconductor.org/packages/release/BiocViews.html#___Software) can ONLY be installed using BiocManager::install("packageName") . On the other hand, CRAN packages can be installed using either BiocManager::install("packageName") or install.packages("packageName"). Thus, BiocManager can install not only Bioconductor packages but also CRAN packages.
Please reach out with any and all questions and please subscribe to Saniya Khullar's YouTube channel to keep learning about Bioconductor packages (Bioconductor playlist: https://youtube.com/playlist?list=PL_3UUp3wcnVYfOToxmCeCKTlFQAGNVgGi), R in general (R playlist: https://youtube.com/playlist?list=PL_3UUp3wcnVasBWwihX6fAisOs6Q7v4T0), and beyond! :)
