R for non programmers II. - data.frames
This follow-up is focused on working with data.frames and doing simple statistics, subsetting, plotting and more.
What we will do
We will do a lot of subsetting and lots of statistical tests on Your data or on movie rating data. That will include manipulating columns, calculating descriptive statistics, plotting vectors etc. We will learn how to create new data.frames from vectors and how to read in text data.
What to do in advance?
Go through past course notebooks at Github
-
If you want to use some of your simple data, bring your own data in text form or download something interesting.
-
Really brush up and practice what we worked on regarding vectors and subsetting.
Important
You will need your own PC with wi-fi module and eduroam access or other internet access that NTK provides. I can’t stress that enough. there is no free Wi-fi in NTK. You either have to have an NTK account or need access to eduroam. If you are PhD sutdents, you should have euroam account provided by your university.
