Sorry, I didn't think carefully about your question on my first reply, so
please ignore it.
Chapter 9 in Morris and Doak (2002) cover vital rate elasticities and
sensitivities (see Box 9.1 for Matlab code
http://www.sinauer.com/PVA/vitalsens.m). Simon, thanks for posting your
code, I will add
After a short exchange with the original questioner, I wrote the following
function to calculate the elasticities of lower level variables in population
transition matrices (Leslie matrices etc.) Perhaps it will be of use to others.
There is no error-checking, so use with care. Users should cons

Dear R-users,
I would like to calculate elasticities and sensitivities of each parameters
involved in the following transition matrix:
A <- matrix(c(
sigma*s0*f1, sigma*s0*f2,
s, v
), nrow=2, byrow=TRUE,dimnames=list(stage,stage))
The command "eigen.analysis" av
