(Weighted) Arithmetic Mean
Generic function for the (trimmed) arithmetic mean, possibly with given weights.
Mean(x, ...) ## S3 method for class 'Freq' Mean(x, breaks, ...) ## Default S3 method: Mean(x, weights = NULL, trim = 0, na.rm = FALSE, ...)

An R object. Currently there are methods for
numeric/logical vectors and date,
date-time and time interval objects. Complex vectors
are allowed for |
weights |
a numerical vector of weights the same length as |
trim |
the fraction (0 to 0.5) of observations to be
trimmed from each end of |
breaks |
breaks for calculating the mean for classified data as composed by |
na.rm |
a logical value indicating whether |
... |
further arguments passed to or from other methods. |
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.
