Spell check ggplot2 plot labels

Due to the way ggplot2 objects are created, this has to be used in a standalone context.

gg_check(gg, dict, ignore)

Arguments

gg	ggplot2 object
dict	a dictionary object or string which can be passed to hunspell::dictionary. Defaults to hunspell::dictionary("sv_SE")
ignore	character vector with additional approved words added to the dictionary. Defaults to hunspell::en_stats

Value

the object that was passed in

Details

Current functionality only looks for misspelled words in the labels of ggplot2 objects. When misspelled words are found, a message is printed with the words and the label that they are in. No messages will be printed if there are no misspelled words.

Examples

library(ggplot2)

df <- data.frame(x=c(20, 25, 30), y=c(4, 4, 4), txt=c("One", "Two", "Three"))

# not piping
ggplot(mtcars, aes(mpg, wt)) +
  geom_point() +
  labs(x="This is some txt", y="This is more text",
       title="Thisy is a titlle",
       subtitle="This is a subtitley",
       caption="This is a captien") -> gg

gg_check(gg)
#> Possible misspelled words in [x]: (This, some)
#> Possible misspelled words in [y]: (This, more)
#> Possible misspelled words in [title]: (Thisy, titlle)
#> Possible misspelled words in [subtitle]: (This, subtitley)
#> Possible misspelled words in [caption]: (This, captien)
