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 H2OFrameiris_hf <- as.h2o(iris)# Look at current ordering of the Species column levelsh2o.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 orderingh2o.levels(iris_hf["Species"])# "virginica" "setosa" "versicolor"## End(Not run)
