Description

Creates a vector of random uniform numbers equal in length to the length of the specified H2O dataset.

Usage

h2o.runif(x, seed = -1)

Arguments

x

An H2OFrame object.

seed

A random seed used to generate draws from the uniform distribution.

Value

A vector of random, uniformly distributed numbers. The elements are between 0 and 1.

Examples

library(h2o)
h2o.init()
prosPath = system.file("extdata", "prostate.csv", package="h2o")
prostate.hex = h2o.importFile(path = prosPath, destination_frame = "prostate.hex")
s = h2o.runif(prostate.hex)
summary(s)

prostate.train = prostate.hex[s <= 0.8,]
prostate.train = h2o.assign(prostate.train, "prostate.train")
prostate.test = prostate.hex[s > 0.8,]
prostate.test = h2o.assign(prostate.test, "prostate.test")
nrow(prostate.train) + nrow(prostate.test)
