Demo of using rnfa R package to scrape trait data - in this example for receptacle traits.

rfna_demo.r

# A web page with taxa names you want to get trait data from
pg1 <- 'http://www.efloras.org/browse.aspx?flora_id=1&start_taxon_id=10074&page=1'


# Get the daughter URLs from the taxa on the page, using doMC to speed things up
urls <- getdaughterURLs(pg1, cores=TRUE, no_cores=2)
  |======================================================================================================| 100%


# Get the receptacle trait state for the taxa
ldply(urls, receptacle, .progress='text')
  |======================================================================================================| 100%
