The data folder contains csv files holding the time / voltage data from
the experiment described in doi.org/10.1109/TCPMT.2022.3209591

This dataset now has a doi too! https://doi.org/10.5258/SOTON/D2389

In those files, a voltage of 0V means that a connection was being made,
1V means it wasn't.  Anything in between means it's probably coming or
going.

The files are named `<pin no.>_<foam hardness>_<size>_9_f_3.csv'.  Pin
number is 1 - 5; foam hardness is 1 - 5 with 1 being softest, 5 hardest;
size is `s' for the small pins, `b' for the big pins.  (9 is axle
diameter; 3 is the version; f is the letter f, stands for foam maybe?  I
can't remember.)

grapher.r is a R script (written for R 4.2.1, but shouldn't be
particularly version sensitive) that generates a scatter plot of each
pin's reliability in each configuration as a PDF on stdout:

$ ./grapher.r > graph.pdf

It probably only works on Linux.  Maybe OSX or WSL, I don't know.
