The “h2o.table” Function in R

• Package: h2o

• Purpose: To compute the frequency table of a column in an H2O data frame.

• General Class: Data Analysis

• Required Argument(s):

• x: H2OFrame. The H2O data frame column for which the frequency table is computed.

• 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")
  
  # Compute frequency table for the 'class' column (5th column)
  freq_table <- h2o.table(data[,5])
  
  # View the frequency table
  print(freq_table)

• In this example, the h2o.table function from the h2o package is used to compute the frequency table for the “class” column in the H2O data frame data. The resulting frequency table is then printed to the console.
