i_median_grp: Impute by group median

In COINr: Composite Indicator Construction and Analysis

Impute by group median

Description

Replaces NAs in a numeric vector with the grouped medians of the non-NA values. Groups are defined by the f argument.

Usage

i_median_grp(x, f, skip_f_na = TRUE)

Arguments

x	A numeric vector
f	A grouping variable, of the same length of x, that specifies the group that each value of x belongs to. This will be coerced to a factor.
skip_f_na	If TRUE, will work around any NAs in f (the corresponding values of x will be excluded from the imputation and returned unaltered). Else if FALSE, will cause an error.

Value

A numeric vector

Examples

x <- c(NA, runif(10), NA)
f <- c(rep("a", 6), rep("b", 6))
i_median_grp(x, f)
