x | an H2OFrame |
---|---|
id_vars | the columns used as identifiers |
value_vars | what columns will be converted to key-value pairs (optional, if not specified complement to id_vars will be used) |
var_name | name of the key-column (default: "variable") |
value_name | name of the value-column (default: "value") |
