Steps to Install R and RStudio
Follow these procedures to install R and RStudio in your system.
Step 1 – Install R
- Download the R installer from https://cran.r-project.org/
- Run the installer. Default settings are fine. If you do not have admin rights on your laptop, then ask you local IT support. In that case, it is important that you also ask them to give you full permissions to the R directories. Without this, you will not be able to install additional packages later
Step 2 – Install RStudio
- Download RStudio: https://www.rstudio.com/products/rstudio/download/
- Once the installation of R has completed successfully (and not before), run the RStudio installer.
- If you do not have administrative rights on your laptop, step 2 may fail. Ask your IT Support or download a pre-built zip archive of RStudio which doesn’t need installing. The link for this is towards the bottom of the download page
- Download the appropriate archive for your system (Windows/Linux only – the Mac version can be installed into your personal “Applications” folder without admin rights).
- Double clicking on the zip archive should automatically unpack it on most Windows machines.
Step 3 – Check that R and RStudio are working
- Open RStudio. It should open a window that looks similar to image 3 below.
- In the left hand window, by the ‘>’sign, type ‘4+5’(without the quotes) and hit enter. An output line reading ‘ 9’ should appear. This means that R and RStudio are working.
- If this is not successful, contact us or your local IT support for further advice Figure 3. Running R with RStudio
Step 4 – Install R packages required for the workshop
- Click on the tab ‘ Packages’ then ‘Install’ as shown in Image 4. Or Tools -> Install packages.
- Install the following packages: mixOmics version 6.1.0, mvtnorm, RColorBrewer, corrplot, igraph. For apple mac users, if you are unable to install the mixOmics imported library rgl, you will need to install the XQuartz software first https://www.xquartz.org/
Check that the packages are installed by typing ‘library(mixOmics)’ (without the quotes) in the prompt and press enter.
- Then type ‘sessionInfo()’ and check that mixOmics version 6.1.0 has been installed.
