Examples

if (FALSE) {
library("spocc")
res <- occ(query = 'Mola mola', from = 'obis', limit = 200)
res_df <- occ2df(res)
sp_extract_gridded(x=res_df)

# pass in lat/lon variable names if needed
names(res_df)[2] <- "mylong"
head(res_df)
sp_extract_gridded(res_df, latitude = "latitude", longitude = "mylong")
}
