You can help me! I have to Open a .RAR file

[dario_gd]

PROBLEM
I would like to open a file directly from a website. the file is .rar . if i decompress the file, inside there are many other folders, each one with sub folders. They all contain integer values ​​that I should use as a single dataset. how can I open the whole file to make it look like just a single dataset?
I would like to have on R a single file, full of all the values, so that I can preprocess and then study

Information about the DataSet

the dataset contains values ​​obtained after a series of experiments to simulate and study potential falls of patients with some disease

this is the website
http://archive.ics.uci.edu/ml/datasets/Simulated+Falls+and+Daily+Living+Activities+Data+Set

What have you done so far? What's your specific problem?
Please try to rephrase your question as a reproducible example, if you have never heard of it before, here is how to do it.

FAQ: What's a reproducible example (`reprex`) and how do I create one?

Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it and feel your pain. Then, hopefully, folks can more easily provide a solution. What's in a Reproducible Example? Parts of a reproducible example: background information - Describe what you are trying to do. What have you already done? complete set up - include any library() calls and data to reproduce your issue. data for a reprex: Here's a discussion on setting up data for a reprex make it run - include the minimal code required to reproduce your error on the data…

What is the tool you use to extract the file on your computer ?

From R, you would surely need several tools. I would

1. Download the file
2. extract the RAR to a folder using a third party tool
3. read the files into R
4. create the dataset

You can do all that from R or just do 1 and 2 outside and began at 3

Yes, your solution is excellent and effective. Maybe I explained myself, (sorry for my English), for the project that I have to carry out, I need to write a code that automatically download the file.rar from the Internet and go to extract the necessary values ​​from the file.

@dario_gd

I need to write a code that automatically download the file.rar from the Internet and go to extract

I think for that you need to call form R a third party tool that deal with RAR files. Using system2 R base tool or sys or processx

I know R for tar and zip file but not for RAR file
