mean(x, ...)
"mean"(x, trim = 0, na.rm = FALSE, ...)
trim = 0
, only.x
before the mean is computed.
Values of trim outside that range are taken as the nearest endpoint.
NA
values should be stripped before the computation proceeds.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.
