The folder of the package I install doesn't show up in the doocuments

So I am doing it as part of my homework. We are asked to install the tm package for data mining. Then, my professor told us to go to "C:\Users\user_name\Documents\R\win-library\4.1\tm", create a file called "texts", and put the documents we download as part of the homework there

This is his instruction

However, when I go to my own win_library, I found no "tm" folder. I have already successfully installed the tm package in my R project and call it using library.

Is this an error? What should I do? Thank you so much.

In recent versions of R, the location of the personal library was moved from Documents to c:\Users\user_name\AppData\Local\R\win-library\.

You can see which paths are used with:

.libPaths()

You can also change the library path temporarily for your session or permanently using libPaths() or environment variables. Details are explained in the ?.libPathshelp page. I would not recommend to do so if you don't know exactly why.

Two additional notes:

• the new location is in a system folder that is normally hidden. It can be made visible by changing an explorer option.
• I don't understand why your professor recommends to save downloaded data into the win_library folder. The folder is "sort of temporary" and in some circumstances it can be a good idea to remove it.
• A good place to store data is indeed under Documents. I recommend my students to store their files there, e.g. under Documents/r_course/lab01/ and so on.
