This vignette demonstrates more advanced features and customization
available in occCite. We recommend you read
vignette("Simple.Rmd", package = "occCite") first, if you
have not already done so.
Querying GBIF can take quite a bit of time, especially for multiple
species and/or well-known species. In this case, you may wish to access
previously-downloaded data sets from your computer by specifying the
general location of your downloaded .zip files.
occQuery will crawl through your specified
GBIFDownloadDirectory to collect all the .zip
files contained in that folder and its subfolders. It will then import
the most recent downloads that match your taxon list. These GBIF data
will be appended to a BIEN search the same as if you do the simple
real-time search (if you chose BIEN as well as GBIF), as was shown
above. checkPreviousGBIFDownload is TRUE by
default, but if loadLocalGBIFDownload is TRUE,
occQuery will ignore checkPreviousDownload. It
is also worth noting that occCite does not currently
support mixed data download sources. That is, you cannot do GBIF queries
for some taxa, download previously-prepared data sets for others, and
load the rest from local data sets on your computer.

Note that you can also load multiple species using either a vector of species names or a phylogeny (provided you have previously downloaded data for all of the species of interest), and you can load occurrences from non-GBIF data sources (e.g. BIEN) in the same query.
In addition to doing a simple, single species search, you can also
use occCite to search for and manage occurrence datasets
for multiple species. You can either submit a vector of species names,
or you can submit a phylogeny! The occCitation function will
return a named list of citation tables in the case of multiple
species.
Here is an example of how such a search is structured, using an unpublished phylogeny of billfishes.
library(ape)
#Get tree
treeFile <- system.file("extdata/Fish_12Tax_time_calibrated.tre", package='occCite')
phylogeny <- ape::read.nexus(treeFile)
tree <- ape::extract.clade(phylogeny, 22)
#Query databases for names
myPhyOccCiteObject <- studyTaxonList(x = tree,
datasources = "GBIF Backbone Taxonomy")
#Query GBIF for occurrence data
myPhyOccCiteObject <- occQuery(x = myPhyOccCiteObject,

When you have results for multiple species, as in this case, you can also plot the summary figures either for the whole search…
or you can plot the results by species!
And then you can print out the citations, separated by species (or not, but in this example, they’re separate).
