Impute by group mean

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

i_mean_grp(x, f, skip_f_na = TRUE)

`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 `NA`s in `f` (the corresponding values of `x` will be excluded from the imputation and returned unaltered). Else if `FALSE`, will cause an error.

A numeric vector

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