Error in BibOptions(): could not find function "BibOptions"

citr::tidy_bib_file() function does not work properly without explicitly loading RefManageR package.

Please see the reproducible code below:

# Download test Rmd and bib files:
utils::download.file("https://jooyoungseo.com/test.Rmd", destfile = "test.Rmd")
utils::download.file("https://jooyoungseo.com/test.bib", destfile = "test.bib")

## Create tidy bib file:
citr::tidy_bib_file(
  rmd_file = "test.Rmd"
  , messy_bibliography = "test.bib"
  , file = "tidy_references.bib"
)
#> Removing 119 unneeded bibliography entries.
#> Error in BibOptions(): could not find function "BibOptions"

# Loading RefManageR

  , file = "tidy_references.bib"
)
#> Removing 119 unneeded bibliography entries.
