Biograph is designed to facilitate the descriptive and statistical analysis of life histories.  It follows a multistate perspective on the life course and conceptualizes the life course as a sequence of states and transitions between states (events). Transitions are governed by transition rates that depend on event counts and exposure times. Transition rates also depend on covariates. Biograph produces useful graphics and computes life-course indicators for individuals and groups. The package structures the data for multistate statistical and demographic modeling of life histories. The package accepts data in a Biograph format. The Doc subdirectory of the package contains a description of how to prepare Biograph objects. It includes several illustrations and R code.

Transition rates are computed from transitions and exposures.Useful graphics and life-course indicators are computed. The package structures the data for multistate statistical and demographic modeling of life histories.

Single linkage clustering and connected component analyses are often performed on biological images. 'Bioi' provides a set of functions for performing these tasks. This functionality is implemented in several key functions that can extend to from 1 to many dimensions. The single linkage clustering method implemented here can be used on n-dimensional data sets, while connected component analyses are limited to 3 or fewer dimensions.

to the anthropic component, accounts for habitat suitability and
provides measures of precision for its estimates.
