Accessing tutorials on GitHub
You might know Github already, which is a platform for sharing code. At first I always found it quite a daunting website, but if you're just downloading someone else's code it is actually a little bit like any filesharing cloud such as dropbox or google drive.
I've made some repositories with tutorials, for example this one: https://github.com/dorienpastoors/flow-cytometry-with-ggplot
Unzip the file in a location of your choice on your own computer. The .rmd file is the script used to generate the HTML file I've embedded on this website. Open the .rmd file in Rstudio. If your working directory is the folder you've unzipped the .zip file in , you can open de RMD file and run it by pressing Run all chunks. That's it :)
You need to install the packages the tutorial requires before you can load them with library()
