Creates a vector of random uniform numbers equal in length to the length of the specified H2O dataset.
h2o.runif(x, seed = -1)
x | An H2OFrame object. |
---|---|
seed | A random seed used to generate draws from the uniform distribution. |
A vector of random, uniformly distributed numbers. The elements are between 0 and 1.
