Value Matching in H2O

Source: R/frame.R

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.

Value

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

if (FALSE) {
h2o.init()
iris_hf <- as.h2o(iris)
h2o.match(iris_hf[, 5], c("setosa", "versicolor"))
