seed	An integer seed.

Value

Examples

generateNA(1:10, p = 0.5, seed = 3345)
generateNA(rep(Sys.Date(), 10))
generateNA(cbind(1:10, 10:1), p = 0.2)
head(generateNA(iris))
head(generateNA(iris, p = 0.2))
head(generateNA(iris, p = c(0, 1, 0.5, 0.5, 0.5)))
head(generateNA(iris, p = c(Sepal.Length = 1)))
head(generateNA(iris, p = c(Species = 0.2, Sepal.Length = 0.5)))
