Arithmetic Mean
Generic function for the (trimmed) arithmetic mean, possibly with given weights.
 Keywords
 univar
Usage
Mean(x, ...)
"Mean"(x, breaks, ...)
"Mean"(x, weights = NULL, trim = 0, na.rm = FALSE, ...)
Arguments
 x
 An R object. Currently there are methods for
numeric/logical vectors and date,
datetime and time interval objects. Complex vectors
are allowed for
trim = 0
, only.  weights
 a numerical vector of weights the same length as
x
giving the weights to use for elements ofx
.  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.  breaks
 breaks for calculating the mean for classified data as composed by
Freq
.  na.rm
 a logical value indicating whether
NA
values should be stripped before the computation proceeds.  ...
 further arguments passed to or from other methods.
Value

If
trim
is zero (the default), the arithmetic mean of the
values in x
is computed, as a numeric or complex vector of
length one. If x
is not logical (coerced to numeric), numeric
(including integer) or complex, NA_real_
is returned, with a warning.If trim
is nonzero, a symmetrically trimmed mean is computed
with a fraction of trim
observations deleted from each end
before the mean is computed.trim
and weights
can't be used together.
