Dear Xavier,
Jeffs answer was to point out two things to you:
1: How to find these functions on your own.
2: These functions are definitely available in R
Good luck,
Marius

Dear Jeff,
Thanks for your fast answer,
I could for sure implement the 2-lines code to calculate the uncertainties,
but I am astonished that a widespread statistics package like R does not
include these very basic quantities.
Regards,
Xavier

- the mean <x> -> mean(x)
- the uncertainty on <x> -> std.error(x) ? Or sd(x)?
- the standard deviation of x -> ?
- the uncertainty on the standard deviation -> ?
Anyone has an idea?
1. Use R's help system to look up 'standard deviation' and 'mean'
e.g.:
??'standard deviation'
??'mean'
For the other two questions, consult your basic stats textbook; the
answers can be calculated from the two above together with the number of
observations.
