[API-users] Some questions from a begginer

Wed Sep 9 20:07:20 CEST 2015

Scott,

That's my very point - that using R and rgbif should be the best path to
take in this case, both because of the easier access to the GBIF API
provided by rgbif and the HUGE data analytical capabilities of R itself. I
had been working on a paper discussing this in the context of conservation
databases (using R/rgbif and a Red-Listed group of mammals as an exemple),
but unfortunately this work has been delayed by unexpected health problems.
Hope it can be the light someday, however.

Best regards,
