h2o.relevel function

Reorders levels of an H2O factor, similarly to standard R's relevel.

Reorders levels of an H2O factor, similarly to standard R's relevel.

The levels of a factor are reordered os that the reference level is at level 0, remaining levels are moved down as needed.

h2o.relevel(x, y)

Arguments

  • x: factor column in h2o frame
  • y: reference level (string)

Returns

new reordered factor column

Examples

## Not run: library(h2o) h2o.init() # Convert iris dataset to an H2OFrame iris_hf <- as.h2o(iris) # Look at current ordering of the Species column levels h2o.levels(iris_hf["Species"]) # "setosa" "versicolor" "virginica" # Change the reference level to "virginica" iris_hf["Species"] <- h2o.relevel(x = iris_hf["Species"], y = "virginica") # Observe new ordering h2o.levels(iris_hf["Species"]) # "virginica" "setosa" "versicolor" ## End(Not run)
