fread

You still remember how to use read.table(), right? Well, fread() is a function that does the same job with very similar arguments. It is extremely easy to use and blazingly fast! Often, simply specifying the path to the file is enough to successfully import your data.

Don't take our word for it, try it yourself! You'll be working with the potatoes.csv (view) file, that's available in your workspace. Fields are delimited by commas, and the first line contains the column names.
