There are some differences in how functions across rgbif behave with respect to many values given to a single parameter. Typically as a user does need to worry about these details, but it can sometimes make a difference.
# multiple API requests occ_search(taxonKey=c(1,212)) occ_data(taxonKey=c(1,212)) # single API request occ_search(taxonKey="1;212")) occ_data(taxonKey="1;212"))
occ_search, there are some parameters you can pass multiple values to in a vector, each value of which produces a different request
c("a","b"). Some parameters allow multiple values to be passed in the same request in a semicolon separated string
"a;b". Only one argument at a time can have multiple values in different requests.
# works occ_search(taxonKey="1;2",basisOfRecord = c("PRESERVED_SPECIMEN","LIVING_SPECIMEN","MATERIAL_CITATION")) occ_search(occurrenceStatus=c("PRESENT","ABSENT")) # will give error occ_search(taxonKey=c(1,2),basisOfRecord = c("PRESERVED_SPECIMEN","LIVING_SPECIMEN","MATERIAL_CITATION")) occ_search(occurrenceStatus="PRESENT;ABSENT")
When using different requests
c("a","b"), you will get back a list equal to the value of your vector. To extract data from multiple different requests, you will need something like the following.
occ_search() arguments can take multiple values, except for the following arguments:
