Determines whether an element satisfying the given predicate exists in each array from an array column (this is essentially a dplyr wrapper for the exists(array<T>, function<T, Boolean>): Boolean built-in Spark SQL function)


hof_exists(x, pred, expr = NULL, dest_col = NULL, ...)


Argument Description
x The Spark data frame to search
pred A boolean predicate
expr The array being searched (could be any SQL expression evaluating to an array)
dest_col Column to store the search result
Additional params to dplyr::mutate
