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.
