Add reference to RefManageR::WriteBib to traits.build tutorials

[bmedlyn]

It may be there already, but I couldn't find it in the help.

A function to generate the citation for a particular trait value. For example I can see all the plant_tolerance_water_logged_soils values come from White_2020 but I couldn't figure out how to find the full citation for this reference. Something like
citation("White_2020") would be ideal

@bmedlyn Thanks for this suggestion.

A quick way to generate a list of citations for the data is to use

austraits$methods %>%
  distinct(source_primary_citation)

Note, if you use the "extract_data" function to extract the datasets/traits you want, then the database retains its traits.build format and the methods dataframe still exists.

But we can also see that it would be very useful to generate a bibtex file of citations from a subsetted database and @fontikar is going to develop an austraits function generate_citation_bibtex that will generate a bibtex file that can be downloaded to merge into citation managers.

@bmedlyn - Fonti and I have just been looking through options and if you run RefManageR::WriteBib on your subsetted database it will create a BibTex file of references that can be opened in reference managers:

This defaults to being stored in the base directory you're in.

austraits %>% extract_dataset(c("Falster", "Wright", "Westoby", "White")) -> austraits_subset
RefManageR::WriteBib(austraits_subset$sources)

Instead of adding a new function to austraits, we'll add this to our tutorial files in traits.build/book. Moving the issue there now.
