[R] Interpreting the eigen value of a population matrix (2nd try)

Thanks for telling me that you could not get my message, I hope this work

so my question was:

I built a population matrix to which I applied the fonction eigen in order
to find the main parameters about my population. I know that the first
eigen value correspond to lambda or exponential growth rate of my
population. My problem is that I want to have the 95% confidence interval
of the specific lambda (1.056 in the case). Is there a way to do that? Are
the other eigen value shown in the output could help me doing it.
I would very appreciate any help.
Thanks for your time
