HELP FOR BEGINNER

I am in a doctoral program and am absolutely clueless about using R for my data science class. We need to use a data set for our final project, and I can pick one from the professor’s selected list, but I cannot even open a single one of the links or files. Can anyone help me? I just need to get started and even be able to open the file in my R Studio, but I can’t even do that. 

Possible data sets to work from are here:

I get an error while requesting the document. But I’d suggest to just contact your professor.
