A function to calcuate the harmonic mean of a set of nonzero numbers.
An object from whose elements the harmonic mean is to be computed.
All the elements of
x are tested as being less than
which is initially set to
.Machine$double.eps ^ 0.5 (about 1.5E-08). The function
set.daeTolerance can be used to change
A numeric. Returns
