Does step 3 of Course Project

This courser project is fro the Getting and Cleaning Data course. I
obtained the mean and standard deviation for each activity/measurement.
Changes documentation

This matches the description on the website.
Add note on renaming activity.

This has been done on step 1.
Change name of column

Instead of `label` I put it as `activity`. I hope this will be more
clear.
Adds note about step 4

This has already been done when I load the original data set. I am still
unsure if this is what they are really asking. It is possible to be more
descriptive than this?
Correct step 2

I understood it wrong. It was not to calculate the meand and standard
deviation for each column but just to obtain the variables that are the
mean and standard deviation of the emasurement.
Keeps the variable w/ only the columns with stats

Instead of adding `subject` and `activity` to the column containing the
mean and stdev measurements, I just added it directly to the
subsetting.
Creates the tidy data set!

Oh, boy! That was hard!

I have created a data frame in which the columns are a identification of
the subject+activity and the rows are the average of the columns that
were a mean or standard deviation measure.
Save the processes data as CSV

It was save as space-spaced file.
Saves the tidy data set
Updates information about the data

I will write more information on the data on the Cookbook.
Change name of the tidy dataset
Transpose the tidy data set

"row should represent an observation and columns should represent
variables"

The rows are the observation made by the smartphone and the columns are
the different observations with the subject+activity.
Save the names of the columns used.

I save it so I can use it as a reference on the Cookbook.
Writes a Cookbook describing the data.
Change the name of script

Just to avoid any complication.
Explain how to run the script.
