missing: Inserts NAs throughout a data frame at random

In bbartholdy/hitchr: A random sample generator based on The Hitchhiker's Guide to the Galaxy

Description

Inserts NAs throughout a data frame at random

Usage

missing(x, na_prob = 0.1, cols = seq_along(x), symm = F)

Arguments

x	Data frame or vector.
na_prob	the probability of missing values per variable in the data frame. Default is 0.1, i.e. each variable will have 10% NAs.
cols	numeric. In which columns to insert NAs. Default is all columns. To leave out the first column, use cols = -1.
symm	logical. whether the missing values should be inserted symmetrically, i.e., whether each column should contain the same number of NAs.

Details

Function is a modified version of 'r_na' and r_na_vector' from the 'wakefield' package. It adds the functionality to add NAs asymmetrically to a data frame, meaning the number of NAs per column will vary.

Value

Returns the original data frame with NAs inserted. The default settings returns a data frame with data missing completely at random.
