error that i can't get to the bottom to. didn't see any issues on dplyr github at quick glance. any thoughts?
input_data %>% mutate(response = NA) Error in mutate_impl(.data, dots, caller_env()) : object '_dplyr_mutate_impl' not found
input_data is a tibble.
I note that the first example in the documentation doesn't work -- same error
mtcars %>% as_tibble() %>% mutate( cyl2 = cyl * 2, cyl4 = cyl2 * 2 )
