No Date in DESCRIPTION file

When trying to cite this package, I get a warning because the description file has no date.

I just thought I'd bring this up given the authors might find it valuable to have a date with the citation to make it easier to cite the package or at least adhere to some common practices for R packages.

> citation("taxa")

To cite package ‘taxa’ in publications use:

  Scott Chamberlain and Zachary Foster (NA). taxa: Taxonomic Classes. R package version 0.3.1.9001. https://github.com/ropensci/taxa

A BibTeX entry for LaTeX users is

  @Manual{,
    title = {taxa: Taxonomic Classes},
    author = {Scott Chamberlain and Zachary Foster},
    note = {R package version 0.3.1.9001},
    url = {https://github.com/ropensci/taxa},
  }

Warning messages:
1: In citation("taxa") :
  no date field in DESCRIPTION file of package ‘taxa’
2: In citation("taxa") :
  could not determine year for ‘taxa’ from package DESCRIPTION file
