Compute the mean and the standard deviation of a data set
represented by the pair of the numeric vectors data and optionally its
frequency vector freq.
Usage
datastats(data, freq = NULL)
Arguments
- data
A numeric vector of a data set.
- freq
A frequency vector corresponding to the data vector.
The default value is NULL, which means all frequencies are one.
Value
The mean and the standard deviation of a data set.
Examples
## Without a frequency data
datastats(mix2gauss$n200)
#> [[1]]
#> [1] 0.4503117
#>
#> [[2]]
#> [1] 1.022398
#>
## With a frequency data
datastats(mix2gaussHist$n200p, mix2gaussHist$n200f)
#> [[1]]
#> [1] 0.2994202
#>
#> [[2]]
#> [1] 1.064247
