Non-exhaustive translation list

[NFA]

Hello,

I cam across this package when searching for a way to easily translate factors in R. The possibility to use a YAML file sold it. However, your package currently requires an exhaustive list of translations to function. Would you consider easing this restriction?

I have a data set of around 200+ factors of which I only need to translate 30-40.

E.g., It would be nice if the following could work:

library(labelmachine)

df <- data.frame(
  pupil_id = rep(1:4, each = 3),
  subject = rep(c("eng", "mat", "Gymnastics"), 4),
  result = c(1, 2, 2, NA, 2, NA, 1, 0, 1, 2, 3, NA),
  stringsAsFactors = FALSE
)

dict <- new_lama_dictionary(
  sub = c(eng = "English", mat = "Mathematics"),
  res = c(
    "1" = "Good",
    "2" = "Passed",
    "3" = "Not passed",
    "4" = "Not passed",
    NA_ = "Missed",
    "0" = NA
  )
)

df_new <- lama_translate(
    df,
    dict,
    subject_lab = sub(subject),
    result_lab = res(result)
  )

Which currently errors with:

Error: Error while calling 'lama_translate': Translation 'sub' could not be applied to column 'subject': The following values in the column variable could not be found in the translation: 'Gymnastics'.

/Kind regards/

Hi @NFA!

Good question. I totally see your use case. My primary consideration is the ux. I am a little bit afraid, that many users may expect wide range of possible behaviours regarding the ordering of the value levels without translation mapping. I need some time to think about the different use cases.
Right now, I am quite busy, but I will have a look into it soon.
