# replace "[e-mail]" with your own email address
bigsearch(genus = "ochotona", rf = "pikaRecords", email = "[e-mail]")

# Pass in curl options for curl debugging
library("httr")
bigsearch(genus = "ochotona", rfile = "pikaRecords", email = "[e-mail]", config=verbose())

# Use more than one year query
bigsearch(class = "aves", year = c(">=1976", "<=1986"),
          rfile = "test-bigsearch1", email = "[e-mail]")
