mean(x, trim=0, na.rm=FALSE)
x
| a numeric vector containing the values whose mean is to be computed. |
trim
|
the fraction (0 to 0.5) of observations to be
trimmed from each end of x before the mean is computed.
|
na.rm
|
a logical value indicating whether NA
values should be stripped before the computation proceeds.
|
trim is zero (the default),
the arithmetic mean of the values in x is computed.
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.
Missing values are ignored.
