As a purely R question though, the OP's suggested code is rather
efficient, though I wouldn't be surprised if a hair more efficiency
couldn't be achieved by pre-allocating the sensorReadings[,2] instead
of calling it twice. Probably a speed/memory trade-off at that point.

I strongly suggest you consult with a local statistician. Your
description is far too vague (to me anyway) to make any sense of and
probably requires a good deal of back and forth between you and a
competent data analyst to pin down what the issues and constraints
are. For example, what constitutes
I have approximately 2.5 million rows from a number of sensor
readings. Having plotted these, I can see a given pattern (say a spike
in the amplitude away from the mean). I would now like to automate
this procedure as we're expecting a great deal more data in the near
future. Is there any package o
