Hi,
I'm using the ineq package to calculate some concentration measures (Gini,

calculate standard error on these measures. If not, is anybody aware of where I
can find a reference on this point?
Thanks.

Thanks to the many R users who convinced me that the sum of NAs should
be zero and gave me a solution if I did not want it to be zero.
Thank you also for the explanations of rounding errors with floating
point arithmetics. I did not expect it. This small error was a real
problem for me as I

Hello Ales,
thank you for your hint regarding names(summary(fit)). Summary(fit) is a
list containig all important results of the Cox-model.
So it helps a lot!
Regarding the results of a Kaplan-Meier estimate summary does not help,
because it does not contain the main results.
Thanks again,

As every employees doesn't encounter every event, a variable number of

The problem is that 90% of your data sit on the boundary. Loess is a
nearest neighbor smoother (using (100 x span) % of the data to estimate at
each point). If you call loess() directly with span=2/3 (the default in
scatter.smooth), or something smaller than about 0.91, you'll see that it

not in the place the person who prepared the binary install of R has it.
Where do you have it installed?
