Dear students,

In the following tutorial we will use the 'tm' package, which is a Text Mining package.

If it is not installed in your RStudio (you can check that by seeing if it appears in your list of 'Packages' in the lower right panel), then please follow these two simple steps:

1. In the console, run the following command:
   install.packages('tm')

2. Then when being asked:
   'Do you want to install from sources the package which needs compilation? (Yes/no/cancel)',
   Enter: 'no'.

I'll see you in the next tutorial, and until then, enjoy Machine Learning!
