An H2OFrame object.

Examples

# NOT RUN {
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)
