  2. Start the "R" program
  3. In the top menu of the window that opens, click “Packages”,then click “Install package(s)”.
  4. Choose a mirror that is close to your geographical location. There should be one for "ACC, Umeå University"
  5. Choose the package you wish to install. You can hold down the CTRL key to highlight and pick multiple packages.
  6. Click "OK"
  7. When your window prompt returns to a ">" the package has finished downloading and installing.

Only do the above once per package.

R packages - loading into R

  1. Start the "R" program if it is not already running
  2. Type “library(RPACKAGE)”, where RPACKAGE should be changed to the name of the specific R package in question. Then press the Enter/Return key.
  3. The package should now be loaded and available.

macOS

R

  1. Pick "Download R for (Mac) OS X" from the nearest download mirror: UmU | Pick different mirror
  2. Choose the latest binary for the base distribution. Note that you may need to install XQuartz if not already installed, if you need to use X11.
  3. Download and install the .pkg file (R-4.0.0.pkg) by double-clicking on it.

RStudio

The base version of RStudio is free. It should suffice for the purposes of the course.

  1. Go to the download page for RStudio and pick the "Free" version
  2. Scroll down a little and pick the macOS 10.13+ .dmg file to download. 
  3. When it has downloaded, double-click it to open, and then drag and drop it to your applications folder.

R packages - installing

You will find a list of R packages here. The link goes to the mirror located in Umeå, but you can find other mirrors from this page.

installed.packages()

NOTE: The list of packages needed for the course is here.

On macOS install.packages works as it does on other Unix-alike systems, but there is an additional type mac.binary (available for the CRAN distribution but not when compiling R from source) which can be passed to install.packages in order to download and install binary packages from a suitable repository. These binary package files for macOS have the extension ‘.tgz’. The R.APP GUI provides menus for installation of either binary or source packages, from CRAN or local files.

There are several procedure for installing R packages, but the simplest is to do it through R:

  1. Find the name of the package you want, for example from the list of R packages
  2. Start Spotlight to find and start the "R" ("R64" if you have) program
  3. Wait for R to start. Now, in the top menu, click “Packages & Data”, then click “Package Installer”.
  4. Click "Get List". The first time it will ask you to choose a mirror. Pick one that is close to your geographical location. There should be one for "ACC, Umeå University". Pick that if you are in Sweden. You can set it as default to avoid being asked every time.
  5. In the pop-up window, make sure "Install Dependencies" is checked. Click "Update All" and "OK".
  6. Choose the package you wish to install from the list. You can search for it as well. Again, make sure "Install Dependencies" is checked.
  7. Click "Install Selected".
  8. When your window prompt returns to a ">" the package has finished downloading and installing.

Only do the above once per package.

Another, faster method of installing packages is the following, though it requires that you know the name of the package:

  1. Start the "R" program
  2. Type “install.packages(“RPACKAGE”)”, where RPACKAGE should be changed to the name of the specific package in question. Then press the Enter/Return key.
  3. If you have not installed other packages during this session, you will be prompted to choose a mirror to download from.
  4. When your window prompt returns to a ">" the package has finished downloading and installing.

      • If R version > 3.5. Using BiocManager
        • 
          if (!requireNamespace("BiocManager", quietly = TRUE))
            install.packages("BiocManager")
          BiocManager::install()
          BiocManager::install(c("graph","Rgraphviz"))
