Let’s look at some of the talking points for the difference between 5 and 7:

library(headliner)

compare_values(5, 7) |> # returns a list
  view_list() # show as a data frame

#>                        value
#> x                          5
#> y                          7
#> delta                      2
#> delta_p                 28.6
#> article_delta            a 2
#> article_delta_p       a 28.6
#> raw_delta                 -2
#> raw_delta_p            -28.6
#> article_raw_delta       a -2
#> article_raw_delta_p  a -28.6
#> sign                      -1
#> orig_values          5 vs. 7
#> trend               decrease

We can string the talking points together like this:

headline(
  x = 5, 
  y = 7, 
  headline = "There was {article_delta_p}% {trend} ({orig_values})"
)

#> There was a 28.6% decrease (5 vs. 7)
