birds1998.samp.cr: Dorazio and Royle's Mark-recapture bird data for 1998

In dill/wisp: Wildlife Simulation Package (wisp)

Description

The data are in an object of class 'sample.cr' containing the matrix of capture histories of species observed at up to 36 locations along a single route of the 'North American Breeding Bird Survey' consisting of 50 sighting locations. While the capture frequency data are real, the capture history data have been fabricated (to be consistent with the capture frequency data) in order to allow estimation in WiSP. (Dorazio and Royle do not provide capture history data.)

• "population"Fabricated population information (consistent with the data) that is required by WiSP - you can ignore it.

• "design"Design information (consistent with the data) that is required by WiSP - you can ignore it.

• "capture"A 67 * 50 matrix of capture histories of 1s and 0s where the rows represent the distinct birds and the columns represent the sighting locations. If bird i was seen at sighting location j then the (i,j)th entry of the capture matrix will be 1; otherwise it will be 0

• parentsInformation that is required by WiSP - you can ignore it.

• createdInformation that is required by WiSP - you can ignore it.

• seedInformation that is required by WiSP - you can ignore it.
