Human activity recognition using smartphone data set problem
The data set definitions are on the page here:

Attribute Information at the bottom

or you can see inside the ZIP folder the file named activity_labels, that has your column headings inside of it, make sure you read the README carefully, it has some good info in it. You can easily bring in a .csv file in R using the read.csv command.

For example if you name you file samsungdata you can open R and run this command:

data &lt;- read.csv("directory/where/file/is/located/samsungdata.csv", header = TRUE)


Or if you are already inside of the working directory in R you can just run the following

data &lt;- read.csv("samsungdata.csv", header = TRUE)


Where the name data can be changed to whatever you want to call your data set.
