Hi Fernando,
your poolaccum class is a list. You can access each element using either
[[ or $ (object$listName). In your case, that would be estimator$jack1. If
you want the mean by rows, you can do
apply(X = estimator$jack1, MARGIN = 1, FUN = mean)
or if you want standard deviation
apply(X = estimator$jack1, MARGIN = 1, FUN = sd)
Someone more knowledgeable will have to weigh in on the ACE/ICE estimators.
Cheers,
Roman

Hello everyone,
I get two questions about richness estimators ..
When I use the command below poolaccum from library (vegan) I have the
following
result
estimator - poolaccum (est, permutations = 100, minsize = 1)
summary (estimator, display = jack1)
N Jackknife 1 2.5% 97.5% Std.Dev
1 5.21 2.000 8.525000 1.79952294
2 9.60 4.2125000 14.50 2.65622958
3 12.116667 6.667 17.508333 2.83689616
4 13.607500 8.500 18.25 2.86595635
5 14.10 9.600 18.60 2.62628516
6 14.751667 9.833 18.17 2.34706099
7 15.408571 10.7142857 18.285714 2.11297296
8 15.54 11.750 19.25 2.10607886
9 15.77 12.311 18.44 1.80268052
10 15.974000 12.900 18.50 1.40105444
11 16.198182 13.3409091 19.022727 1.36031920
12 16.089167 14.833 17.67 0.93069726
13 16.012308 14.8461538 17.692308 0.72956962
14 15.857143 15.8571429 15.857143 0.
1) I would like to know which command I have to use to get the mean and
standard deviation ... What command I use to use these data as vectors
separately ..
2) For the ACE and ICE estimators they consider the abundance of 10
individuals
or incidence in 10 samples as being rare, I wonder if anyone
know how to change this value.
Thank you for your attention.
Best regards,
FERNANDO RODRIGUES DA SILVA
