Scaling and Centering of an H2OFrame

Source: R/frame.R

Centers and/or scales the columns of an H2O dataset.

h2o.scale(x, center = TRUE, scale = TRUE, inplace = FALSE)

Arguments

x

An H2OFrame object.
center

either a logical value or numeric vector of length equal to the number of columns of x.
scale

either a logical value or numeric vector of length equal to the number of columns of x.
inplace

a logical values indicating whether directly overwrite original data (disabled by default). Exposed for backwards compatibility (prior versions of this functions were always doing an inplace update).

Examples

if (FALSE) {
library(h2o)
h2o.init()
iris_hf <- as.h2o(iris)
summary(iris_hf)

# Scale and center all the numeric columns in iris data set
iris_scaled <- h2o.scale(iris_hf[, 1:4])
}
