Generic function for the (trimmed) arithmetic mean, possibly with given weights.

`Mean(x, ...)`# S3 method for Freq
Mean(x, breaks, ...)

# S3 method for default
Mean(x, weights = NULL, trim = 0, na.rm = FALSE, ...)

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 non-zero, 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 at the same time.

- x
An object. Currently there are methods for numeric/logical vectors and date, date-time and time interval objects. Complex vectors are allowed for

`trim = 0`

, only.- ...
further arguments passed to or from other methods.

- breaks
breaks for calculating the mean for classified data as composed by

`Freq`

.- weights
a numerical vector of weights the same length as

`x`

giving the weights to use for elements of`x`

.- 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.
