Arguments

x	auk_ebd object; reference to EBD file created by auk_ebd().
time	character; 2 element character vector giving the range of times in 24 hour format, e.g. "06:30" or "16:22".

Value

An auk_ebd object.

Examples

# only keep checklists started between 6 and 8 in the morning
system.file("extdata/ebd-sample.txt", package = "auk") %>%
  auk_ebd() %>%
  auk_time(time = c("06:00", "08:00"))
