10.4 Exercise

1. How can you just return the contents of the first cell in splits?

simple_split[["splits"]][[1]]
## <2199/731/2930>
simple_split[[1, 1]]
## <2199/731/2930>
simple_split %>% magrittr::extract2("splits") %>% 
  magrittr::extract2(1)
## <2199/731/2930>
simple_split %>% purrr::pluck("splits", 1)
## <2199/731/2930>

2. What’s the difference between the output of these 2 results?

simple_split %>%
  pluck("splits")
## [[1]]
## <2199/731/2930>

simple_split %>%
  pluck("splits", 1)
## <2199/731/2930>
