Description

Randomly amputes data (MCAR).

Usage

amputeData(data, perc = 0.1, cols = names(data))

Arguments

data	The data to be amputed
perc	A scalar. The percentage (0-1) to be amputed.
cols	The columns to ampute.

Value

The same dataset with random values in cols set to NA.

Examples

data(iris)
head(iris,10)

ampIris <- amputeData(iris)
head(ampIris,10)
