TIBHannover/BacDiveR: Fix NULL comparison bug

This R package provides a programmatic interface for the Bacterial Diversity Metadatabase (Söhngen et al. 2014 & 2016 ) of the DSMZ (German Collection of Microorganisms and Cell Cultures). BacDiveR helps you to conduct your microbial research better and faster, by:

• downloading the BacDive datasets you want to investigate off-line, and by

• providing you with a way to document and report your searches and downloads, in a reproducible manner (.R scripts and/or .Rmd files).

It was also built to serve as a demonstration object during TIB's "FAIR Data & Software" workshop.

See TIBHannover.GitHub.io/BacDiveR for more details, /news there for the changelog, and GitHub.com/TIBHannover/BacDiveR for the latest source code.
