The (weighted) Interquartile Range

computes interquartile range of the x values. Weights are supported.

IQRw(x, weights = NULL, na.rm = FALSE, type = 7)

Arguments

x

a numeric vector.

weights

an optional numeric vector giving the sample weights.

na.rm

logical. Should missing values be removed?

type

an integer selecting one of the many quantile algorithms, see Quantile().

Details

This implementation is based on Quantile() function, which allows to define weights.

Examples

x <- c(3.7,3.3,3.5,2.8)
w <- c(5, 5, 4, 1)/15

IQRw(x=x, weights=w)
