leslie {epimdr2} | R Documentation |
A function to calculate asymptotic growth, sensitivity and elasticity for age-structured populations
Description
A function to calculate asymptotic growth, sensitivity and elasticity for age-structured populations
Usage
leslie(L)
Arguments
L |
the Leslie matrix |
Value
A list consisting of the following components:
lambda |
the dominant eigen value of the Leslie matrix. |
right.eigenvector |
the dominant right eigen vector of the Leslie matrix, proportional to the stable age-distribution. |
left.eigenvector |
the dominant left eigen vector of the Leslie matrix representing the age-specific reproductive values. |
elasticity |
the elasticities. |
sensitivity |
the sensitivities. |

Examples
fa<-c(0, 0.5, 1.2)
sa<-c(0.8, 0.8, 0)
L<-matrix(0, nrow=3, ncol=3)
#inserting fa vector in first row
L[1,]<-fa
#inserting sa in the subdiagonal:
L[row(L)==col(L)+1] <-sa[1:2]
