Note: There should be a possibility to supply (as an argument to
Raman2df()) a custom sampleid which should then override the regexp-
based algorithm (only if that argument was supplied).
Function takes a potential and its reference electrode, and converts to a specified reference electrode scale, either another or the same.
I made it to simplify converting between different reference electrode scales in running text.
Celsius2Kelvin()
Kelvin2Celsius()
Including very crude error checks (checks that supplied temperature
is not below absolute zero, if so, sets it to absolute zero).
Idea: would be nice if function returned same number of significant
digits as it received.
