skewness(x, na.rm=FALSE)
x
| a numeric vector containing the values whose skewness is to be computed. |
na.rm
| a logical value indicating whether NA values should be stripped before the computation proceeds. |
x
.
If N = length(x), then the skewness of x is defined as
N^(-1) sd(x)^(-3) sum_i (x_i - mean(x))^3
x<-rnorm(100) skewness(x)
