An rgbif
user asked how to combine occurrence data from occ_search()
, including how to deal with taxa that have no occurrence data results
Make a species list and pass it to occ_data()
library("rgbif")
spp <- c("Abrodictyum laetum", "Abrodictyum brassii", "Abrodictyum boninense")
x <- occ_data(scientificName = spp, hasCoordinate=TRUE, limit = 10)
x
Looking at the output, one of the three taxa had no occurrence data results, and two did.
x$`Abrodictyum boninense`$data
#> NULL
Combine data using dplyr::bind_rows()
(similarly, you can use data.table::rbindlist
). Either of these options will be able to handle NULL
's, and will fill columns so that if data.frame’s have different sets of column names they will still bind together.
library("dplyr")
bind_rows(lapply(x, "[[", "data"))

The above works similarly for occ_search()
.
