Annual cumulative sums from time series
...ly
into annual pieces so I can cumsum() every year separately.
I have the strong hope that the solution is one of these
one-liners which leave the students with eyes wide open in surprise and
makes them true believers in the power of the command-line 8-).
Thanks & Greetings

Simple spectral analysis
...final aim would be to
get the periodogram (and the residuals from the reassembled data set...)
Thanks and greetings,

The data set:
air = read.csv("http://www.hydrology.uni-kiel.de/~schorsch/air_temp.csv")
airtemp = ts(T_air, start=c(1989,1), freq = 365)
plot(airtemp)

Strange update problem 3.0.5->3.0.6 with XP-Clients
...es (read error in xp). I have tested it with
Xp-Prof SP1 und SP2 (domain-login) and XP-Home (no domain login).
Any hints what I should do? (I am no samba expert - until now it just
worked)
(bugreport to debian is submitted, 3.0.6-2 did not solve the problem)
Thanks & Gruss

Getting *types* of arguments?
...ments of a function *with* variable/parameter types?
formals() gives me the names of the parameters, but says
nothing about the parameter type it expects (I know I can always use the
help function).
I would like somthing like
$x: vector or data.frame...
Thanks in advance...

Teaching R in 40 minutes. What should be included?
If _you_ were asked to give a 40 minute dog and pony show about R for
a group of scientists ranging from physicists to geographers what
would you put in? These people want to know what R can do.
I'm thinking about something like:
A. Overview
B. data structures
C. arithmetic and manipulation
D. reading data
E. linear models using glm
F. graphics
G. programming
H. other tricks like rpart or
