The functions of the script

The script will do the PCA for the Linear-Accelerator data from the csv file we got from the Android App.

Then it will filter the result of the PCA and draw three plots about the Phone A's movement, Phone B's movement and the correlation between the two dataset.

Make sure you have installed the R language in your system. If not, please download it from R-Project offical website

Then please install the R packages via the install.packages() command:

How to use this script

Put the two csv file in the folder and rename them (or modified the script line 8 and 9)

Open the terminal (PowerShell, Tilix, iTerm2, whatever)

The plot will create in the folder named "output_plot.pdf", the importance of components of PCA will output in the terminal.
