# operating on `taxon` objects
out <- make_taxon(genus="Poa", epithet="annua", authority="L.",
   family='Poaceae', clazz='Poales', kingdom='Plantae', variety='annua')
# get single name
out %>% pick(family)
out %>% pick(genus)
out %>% pick(species)
out %>% pick(species) %>% name()
out %>% pick(species) %>% uri()
# get range of names
out %>% span(kingdom, genus)

# operating on taxonomic data.frames
df <- data.frame(class=c('Magnoliopsida','Magnoliopsida','Magnoliopsida',
                         'Magnoliopsida','Magnoliopsida','Magnoliopsida'),
         order=c('Asterales','Asterales','Fagales','Poales','Poales','Poales'),
         family=c('Asteraceae','Asteraceae','Fagaceae','Poaceae','Poaceae','Poaceae'),
         genus=c('Helianthus','Helianthus','Quercus','Poa','Festuca','Holodiscus'),
         stringsAsFactors = FALSE)
(df2 <- taxon_df(df))

## select single taxonomic class
df2 %>% pick(order)
df2 %>% pick(family, genus)

## filter to get a range of classes
df2 %>% span(order, genus)
df2 %>% span(family, genus)
