dataset_citations returns dataset citations as text or as 
"bibentry" objects.
Usage
dataset_citations(datasets = c(), astext = TRUE)Arguments
- datasets
- character vector. Code of the datasets. When no datasets are provided (default), then all citations are returned. 
- astext
- logical. When - TRUE(default), then citations are returned as text otherwise they are returned as "- bibentry" objects.
Value
Either a character vector or a list of 
  "bibentry" objects.
Details
Note that in order to generate a full list of citations it is
  preferable to run the layer_citations function.
Examples
# print the Bio-ORACLE citation
print(dataset_citations("Bio-ORACLE"))
