Usage

Format

A list consisting of 2 elements

removal

A MT x J data.frame of counts of individuals removed at each trap location for each primary period where ‘M' is the number of traps, 'T’ is the number of primary periods and 'J' is the number of secondary periods (nights). The data.frame must have an additional column named session indicating the primary period for each observation. The remaining columns contain the number removed during each of the J secondary periods

traps

a data.frame with M rows of trap locations

Details

A simulated example dataset of removal sampling of rabbits from an open population on San Nicolas Island, California. The data consist of the counts of rabbits removed from each of 100 traps spaced randomly on the island over 8 separate removal (primary) periods. For each primary period, traps were set for 4 consecutive nights (secondary period). Primary period trapping was undertaken every 3 months over a two year period and hence, it would be unreasonable to expect the population to be closed. Hence, these data require analysis with an open population removal model (i.e. 'remMNO()').
