retrival limit downstram/gbif_downstream, documentation

[azizka]

Hi Scott, I am teaching a course using taxize (still awesome, thanks!), we are trying to use downstream/gbif_downstream to get species names in different taxa from the GBIF backbone.

1. Would it be possible to add to the documentation of gbif_downstream, that there is a hard limit of 1000 names to be returned (See code below for Piper, which stops at 1000 names with epitheton f*)? We figured out to use the at argument after a while as a workaround, but it would be nice if the limit and the solution were clear from the documentation.

2. If possible it would be nice to learn from the downstream documentation already that downstream has a default limit of 100 names (via the default in gbif_downstream.

Thanks & sorry if we missed anything

code example

library(taxize)
library(tidyverse)

ID<- get_gbifid_("Piper", method="backbone")%>% 
  bind_rows() %>%
  filter(matchtype == "EXACT" & status == "ACCEPTED") 

splist <- gbif_downstream(id = ID$usagekey,
                          limit = 2000,
                          method = "lookup",
                          downto = "species",
                          rows = NA)[[1]]

Thanks, having a look
