Description

Get the index of the max value in a column or row

Usage

h2o.which_max(x, na.rm = TRUE, axis = 0)

which.max.H2OFrame(x, na.rm = TRUE, axis = 0)

which.min.H2OFrame(x, na.rm = TRUE, axis = 0)

Arguments

x

An H2OFrame object.

na.rm

logical. Indicate whether missing values should be removed.

axis

integer. Indicate whether to calculate the mean down a column (0) or across a row (1).

Value

Returns an H2OFrame object.

See Also
