• [x] update mentions of eml_nsf_to_project( to include argument , eml_version = "2.2.0")
• [ ] add a citation function?
• [x] units need to install devtools::install_github("ropensci/emld") because the fix is not on CRAN yet (reference issue: https://github.com/ropensci/emld/issues/56) -> fixed in most recent version devtools::install_github("ropensci/emld")
