Example capture-recapture data from a study of European dippers.
data(dipper.data)
A data frame containing 294 capture histories and the sex designation of birds captured. Capture indicators are either 0 = not captured, 1 = captured, or 2 = captured but died and not released back into the population. Columns in the data frame are:
h1h2h3h4h5h6h7malesfemalesThis is a popular capture-recapture example data set. It has been analyzed by Lebreton et al. (1992) Amstrup et al. (2005) and others.
dipper.males is a vector indicating male birds. I.e., dipper.males <- dipper.data\$males
dipper.histories is a matrix of just the capture history columns h1 - h7, extracted
from dipper.data and made into a matrix. This matrix is fed directly into F.cr.estim.
