The “h2o.dim” Function in R

• Package: h2o

• Purpose: To retrieve the dimensions (number of rows and columns) of an H2O data frame.

• General Class: Data Retrieval

• Required Argument(s):

• x: H2OFrame. The H2O data frame for which dimensions are retrieved.

• Notable Optional Arguments:

• None

• Example (with Explanation):

• # Load necessary package
  library(h2o)
  
  # Initialize H2O
  h2o.init()
  
  # Load a sample dataset
  data <- h2o.importFile("https://s3.amazonaws.com/h2o-public-test-data/smalldata/iris/iris_wheader.csv")
  
  # Retrieve dimensions of the dataset
  dimensions <- h2o.dim(data)
  
  # Print the dimensions
  print(dimensions)

• In this example, the h2o.dim function from the h2o package is used to retrieve the dimensions (number of rows and columns) of the iris dataset loaded into an H2O data frame. The retrieved dimensions are then printed.
