h2o.insertMissingValues function

Insert Missing Values into an H2OFrame

Insert Missing Values into an H2OFrame

Randomly replaces a user-specified fraction of entries in an H2O dataset with missing values.

h2o.insertMissingValues(data, fraction = 0.1, seed = -1)

Arguments

  • data: An H2OFrame object representing the dataset.
  • fraction: A number between 0 and 1 indicating the fraction of entries to replace with missing.
  • seed: A random number used to select which entries to replace with missing values. Default of seed = -1 will automatically generate a seed in H2O.

Returns

Returns an H2OFrame object.

WARNING

This will modify the original dataset. Unless this is intended, this function should only be called on a subset of the original.

Examples

## Not run: library(h2o) h2o.init() iris_hf <- as.h2o(iris) summary(iris_hf) iris_miss <- h2o.insertMissingValues(iris_hf, fraction = 0.25) head(iris_miss) summary(iris_miss) ## End(Not run)
