02.Caswell {popbio}R Documentation

Converted Matlab functions from Caswell (2001)

Description

Chapter 2. Age-classified matrix models

pop.projection
section 2.2. Projection of population growth rates. See stage.vector.plot to plot stage (or age) vectors

Chapter 4. Stage-classified matrix models

eigen.analysis
section 4.8. Computation of eigenvalues and eigenvectors. Returns the dominant eigenvalue (section.4.4), stable stage distribution (section 4.5), reproductive value (section 4.6), and damping ratio (section 4.7)

Chapter 5. Events in the Life Cycle

fundamental.matrix
section 5.3.1. Calculate age-specific survival from a stage classified matrix using the fundamental matrix N
net.reproductive.rate
section 5.3.4. Calculate the net reproductive rate of a stage classified matrix using the dominant eigenvalue of the matrix R.
generation.time
section 5.3.5. Calculate the generation time of a stage-classified matrix

The whale dataset includes code to calculate age-specific survival and fertility curves (figure 5.1 and 5.2).

Chapter 6. Parameter estimation

projection.matrix
section 6.1.1. Estimate vital rates and construct a projection matrix using transtion frequency tables
QPmat
section 6.2.2. Construct a projection matrix from a time series of individuals per stage using Wood's quadratic programming method. Requires quadprog library.

See the Rcapture package for capture-recapture methods described in section 6.1.2.

Chapter 9. Sensitivity analysis

eigen.analysis
section 9.1, and 9.2. Calculate sensitivities and elasticities. The examples in the teasel and tortoise datasets also include code to sum elasticities and create figures like 9.3, 9.4, and 9.11.

See the demogR package for the second derivative function described in section 9.7.

Chapter 15. Demographic stochasticity

multiresultm
section 15.1.3. Incorporate demographic stochasticity into population projections. The example uses the whale dataset to create a plot like figure 15.3.
