require(dplyr, quietly = TRUE, warn.conflicts = FALSE)
my_cars <- c("mazda", "Merc 2.*")
mtcars %>%

filter_any(car, patterns = my_cars, ignore.case = T) %>%
select(-car)
starwars %>% data.frame() %>%
filter_any(species,patterns = c("human","droid"), ignore.case = T, invert = T) %>%
select(name, species) %>%
