Value Matching in H2O

match and %in% return values similar to the base R generic functions.

h2o.match(x, table, nomatch = 0, incomparables = NULL)

match.H2OFrame(x, table, nomatch = 0, incomparables = NULL)

x %in% table

Arguments

x	a categorical vector from an H2OFrame object with values to be matched.
table	an R object to match `x` against.
nomatch	the value to be returned in the case when no match is found.
incomparables	a vector of calues that cannot be matched. Any value in `x` matching a value in this vector is assigned the `nomatch` value.

Returns a vector of the positions of (first) matches of its first argument in its second

# NOT RUN {
h2o.init()
iris_hf <- as.h2o(iris)
h2o.match(iris_hf[, 5], c("setosa", "versicolor"))
