library(headliner)compare_values(5,7) |># returns a listview_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 decreaseWe 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)Seehere for a longer introduction.
