Calculates mean pH from a vector of pH values by averaging [H+] rather than numerical pH values.
mean_pH(pH, na.rm = FALSE, ...)
a numeric vector of pH values.
a logical value indicating whether NA values should be stripped before the computation proceeds.
further arguments passed to or from other methods.
Since pH is on a logarithmic scale, averaging pH values directly does not provide the true arithmetic mean of what is likely truly important to the organism, [H+] (however, see Boutilier and Shelton 1980). Thus, the pH values are converted to [H+] then averaged and converted back to a mean pH value.
