Univariate Imputation

Fills missing values of a vector, matrix or data frame by sampling with replacement from the non-missing values. For data frames, this sampling is done within column.

Usage

imputeUnivariate(x, v = NULL, seed = NULL)

Arguments

x

A vector, matrix or data frame.

v

A character vector of column names to impute (only relevant if x is a data frame). The default NULL imputes all columns.

seed

An integer seed.

Value

x with imputed values.

Examples

imputeUnivariate(c(NA, 0, 1, 0, 1))
#> [1] 0 0 1 0 1
head(imputeUnivariate(generateNA(iris)))
