Dear Ola,
I think you spotted a small bug in *package* fCalendar.
Explicit specification should prevent autodetection of the date
format, which is not the case for fCalendar v251.70, instead
autodetection is done at least once (twice, if actually appropriate).

You may find screen useful, see e.g.

for a short description how to use it with R (reattaching works via
screen -r). (Maybe your sysadmin has to install screen first, it's a
unix tool.)

I think there is still a small bug which I reported some time ago to

Folks,
I'm a bit puzzled by the fact that if I generate 100,000 standard
normal variates using rnorm() and perform the Jarque-Bera on the
resulting vector, I get p-values that vary drastically from run to
run. Is this expected?
Yes.
Surely the p-val should be close
If monthly should aggregate per -mm combination, you could try
something like
aggregate(x$z,list(cut(as.Date(x$Date),m)),mean)
for monthly aggregation and
aggregate(x$z,list(cut(as.Date(x$Date),y)),mean)
for yearly means.
If monthly aggregation should aggregate over different years
Did you have a look at the posting guide?
We have to guess that you are using some version of fOptions in some
version of R under some OS, and that you run code from the examples
section of ?MonteCarloOption relying on other code from that section
which is not mentioned at all. Given that these
readLines (which is mentioned in the See also section of ?scan with
the hint to read a file a line at a time) should work.

Hi,
I would like to be able to count a sequence of numbers. For example, given a
vector of the following integers
(1,1,1,2,2,2,2,3,3,3,3,3,3,1,1,1,1, 3,3)
the function would return

Does anyone have any cool ideas to solve this?
Maybe not the most

I need to generate a sequence of the form:

That is: starting with 4, make a 3 numbers sequence, jump 6, then another 3

I can create a whole vector with:
