Now let's start our `dirty but fun` work to install R in you computer. I've used R in three different computers: R or Linux and Mac OS at home and R for Windows at the Uni, and here's some of my notes:
Computer specification: There's no `must` in this part. I've seen someone who uses Intel Celeron to run R, and it still runs well at some level as a function of data size and complexity. Basically you would need faster processor and larger RAM as you grow your data size. If you have a plan to purchase a new computer, I would suggest to get a i5 equivalent and 4 GB of RAMs. You can buy better specification if your budget allows you to. Otherwise, just use your current PC and maximise it.
Operating System (OS): R runs on all major OS: Linux (like Ubuntu, Fedora etc), Mac OS, and off course Windows. Don't worry, they will look and work at the same manner, as long as you have the sama R base and R Studio version.
