Getting PDFs from pre-print servers

Just get some PDFs

In this vignette we go through the process of getting some PDFs. First we need to set-up a tibble of papers that we are interested in.

library(heapsofpapers)

two_pdfs <-
  tibble::tibble(
    locations_are = c("https://osf.io/preprints/socarxiv/z4qg9/download",
                      "https://osf.io/preprints/socarxiv/a29h8/download"),
    save_here = c("competing_effects_on_the_average_age_of_infant_death.pdf",
                  "cesr_an_r_package_for_the_canadian_election_study.pdf")
  )

Now we want to download those PDFs (this will just download them into the current working directory).

heapsofpapers::get_and_save(
  data = two_pdfs,
  links = "locations_are",
  save_names = "save_here"
)

Get some PDFs and save them in a particular folder

Now it may be useful to have the PDFs saved into a specific folder. So this time make a folder ‘inputs’ in the current working directory. Those same PDFs will now be saved into that folder.

heapsofpapers::get_and_save(
  data = two_pdfs,
  links = "locations_are",
  save_names = "save_here",
  dir = "inputs"
)

Check which PDFs already exist in a particular folder

Now we can check which of these we have.

heapsofpapers::check_for_existence(data = two_pdfs, 
                                   save_names = "save_here",
                                   dir = "inputs")
