  1. #linear.r takes raw data time series index associated with some variable 'y' and uses 1 minute interpolation and 15 minute sliding average to format data. User can comment/uncomment code blocks to disable/enable features respectively. Raw data must be located on desktop as cooling.txt, IT.txt, lighting.txt, or losses.txt
