Generic function for the (trimmed) geometric mean.
Arguments
- x
A nonnegative vector.
- zero.rm
a logical value indicating whether zero values should be stripped before the computation proceeds.
- trim
the fraction (0 to 0.5) of observations to be trimmed from each end of x before the mean is computed. Values of trim outside that range are taken as the nearest endpoint.
- na.rm
a logical value indicating whether NA values should be stripped before the computation proceeds.
