h2o.exportFile: Export H2O Data Frame to a File.

Description

Export an H2O Data Frame (which can be either VA or FV) to a file. This file may be on the H2O instance's local filesystem, or to HDFS (preface the path with hdfs://) or to S3N (preface the path with s3n://).

Usage

## Default method:
h2o.exportFile(data, path, force = FALSE)

Arguments

path

The path to write the file to. Must include the directory and filename. May be prefaced with hdfs:// or s3n://. Each row of data appears as one line of the file.

force

(Optional) If force = TRUE any existing file will be overwritten. Otherwise if the file already exists the operation will fail.

Value

• None. (The function will stop if it fails.)

Examples

library(h2o)
localH2O = h2o.init()
irisPath = system.file("extdata", "iris.csv", package = "h2o")
iris.hex = h2o.importFile(localH2O, path = irisPath)
h2o.exportFile(iris.hex, path = "/path/on/h2o/server/filesystem/iris.csv")
h2o.exportFile(iris.hex, path = "hdfs://path/in/hdfs/iris.csv")
h2o.exportFile(iris.hex, path = "s3n://path/in/s3/iris.csv")
