In this video, I'm going to briefly show how you can install R on the Mac. It's a very simple process, it only takes a few steps. So the first thing you need to do is open your web browser and go to CRAN, this is the Comprehensive R Archive Network, and you'll see that there are a number of options for you to download here for different platforms. Matt Denny explains how to successfully install R on a Mac by first installing XCode Command line tools and then going to the R website to download and insta. Of course to check what your R Studio version is you just need to click on the Help menu item and then click on 'About RStudio'. To update R, go to CRAN and download the latest version and run the install. When you restart RStudio or R Console it should automagically detect and use the new R version. R-Studio for Mac install/uninstall/register Install: 1. Double-click the downloaded installation file. Move R-Studio.app to the Applications folder Click image to enlarge. Go to Applications in Finder and double-click R-Studio.app to start the program.

After installing R and RStudio, the question is now how to start using R/RStudio. In this article, we'll describe how to run RStudio and to set up your working directory.

Note that, it's possible to use R outside or inside RStudio. However, we highly recommend to use R inside RStudio. RStudio allows users to run R in a more user-friendly environment.

Under Windows and MAC OSX

For the first time you use R, the suggested procedure, under Windows and MAC OSX, is as follow:

1. Create a sub-directory, say R, in your 'Documents' folder. This sub-folder, also known as working directory, will be used by R to read and save files.

2. Launch R by double-clicking on the icon.

3. Specify your working directory to R:
   • On Windows: File –> Change directory
   • On MAC OSX: Tools –> Change the working directory

Under Linux

1. Open the shell prompt

2. Create a working directory, named 'R', using 'mkdir' command: Mac shell shocked zip.

1. Start the R program with the command 'R':

$ R Pillars of eternity guide.

How To Update R And Rstudio On Mac

1. To quit R program, use this:

$ q()

Using R inside RStudio is the recommended choice.

Launch RStudio under Windows, MAC OSX and Linux

After installing R and RStudio, launch RStudio from your computer 'application folders'.

RStudio screen

RStudio is a four pane work-space for 1) creating file containing R script, 2) typing R commands, 3) viewing command histories, 4) viewing plots and more.

1. Top-left panel: Code editor allowing you to create and open a file containing R script. The R script is where you keep a record of your work. R script can be created as follow: File –> New –> R Script.

2. Bottom-left panel: R console for typing R commands

3. Top-right panel:
   • Workspace tab: shows the list of R objects you created during your R session
   • History tab: shows the history of all previous commands
4. Bottom-right panel:
   • Files tab: show files in your working directory
   • Plots tab: show the history of plots you created. From this tab, you can export a plot to a PDF or an image files
   • Packages tab: show external R packages available on your system. If checked, the package is loaded in R.

For more about RStudio read the online RStudio documentation.

Set your working directory

Recall that, the working directory is a folder where R reads and saves files.

Change your working directory

You can change your working directory as follow:

1. Create a sub-directory named 'R' in your 'Documents' folder

2. From RStudio, use the menu to change your working directory under Session > Set Working Directory > Choose Directory.
3. Choose the directory you've just created in step 1

It's also possible to use the R function setwd(), which stands for 'set working directory'.

For Windows, the command might look like :

Note that, if you want to know your current (or default) R working directory, type the command getwd(), which stands for 'get working directory'.

Set a default working directory

A default working directory is a folder where RStudio goes, every time you open it. You can change the default working directory from RStudio menu under: Tools –> Global options –> click on 'Browse' to select the default working directory you want.

Each time you close R/RStudio, you will be asked whether you want to save the data from your R session. If you decide to save, the data will be available in future R sessions.

I am trying to import three really big files (each file size >100GB) to R Studio but it complains of memory. I am using this version:

I tried increasing the memory limit by using (.Renviron) on terminal but it gives the same error.

How much actual memory does your mac have? There is no substitute for not having enough RAM unfortunately.

I don't think this is going to work as is.

Edit: @zx5784's solution of using virtual memory on disk may work. With such large data set you may need to have patience in equally large amounts.

What kind of data is this? Alternatives:

• HPC with tonnes of memory
• Load data in chunks, do stuff, save results, load another chunk etc.
• Use packages that uses hard drive as memory and 'pretend' to have it as full object in R, e.g.: 'bigmemory' package.

See CRAN TaskView for HPC: Large memory and out-of-memory data

These are vcf files.

Do you need all the data at once, maybe slim it down first: filter on Samples, on Variants, or split on Chromosomes, etc. See bcftools for manipulating VCFs.

What operation are you trying to do with them? Perhaps there are command line alternatives that can be used instead of R. Are these files compressed or not?

I am trying to use them for Upset R plot and these are not compressed.

Is it to show overlapping Variants or Samples? Again you can get that info using bcftools, then file will be manageable for R.
