mean: Arithmetic Mean

In msberends/certedata: Tools for Data Analysis at Certe

Description

Generic function for the (trimmed) arithmetic mean.

Usage

mean(x, ..., na.rm = TRUE)

Arguments

x	An R 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.
na.rm	a logical value indicating whether NA values should be stripped before the computation proceeds.

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 non-zero, a symmetrically trimmed mean is computed with a fraction of trim observations deleted from each end before the mean is computed.
