For each element in vector do...
Dear R useRs,
I have a vector with positive and negative numbers:
A=c(0,1,2,3,0,4,5)
Now if i-th element in vector A is > 0, then i-th element in vector B
is a+1
else i-th element in vector b=a (or 0)
vector A: 0 1 2 3 0 4 5
vector B: 0 2 3 4 0 5 6
What's the right way to do this. I still have some problems with for and
if statements...
Cheers, Andrej

Regex question
Dear R useRs,
is there any simple, build in function to match specific regular
expression in data file and write it to a vector. I have the following
text file:
*NEW RECORD
*ID-001
*AB-text
*NEW RECORD
*ID-002
*AB-text
etc.
Now I have to match all ID fields and print them to a vector:

etc.
I know that this is very simple with Perl or R-Perl interface, but if
possible, I want to do

How to shadow 'power' area?
Dear all,
Suppose I plot two normal distributions (A and B) side by side and add
vertical line which hipotheticaly represent alpha value; e.g.:
x <- seq(-3.5,5, length=1000)
y <- dnorm(x)
# Plot distribution A
plot(y~x, type='l',axes=F,xlab="",ylab="",lwd=2)
# Plot distribution B
y2 <- dnorm(x-1.5)
lines(y2~x,lwd=2)
# Plot vertical line for alpha value

Ability estimates for partial credit model
Dear all,
I'm working on ability estimates using Rasch model. Using the "ltm"
package, the procedure is quite simple:
## Factor Scores for the Rasch model
fit <- rasch(LSAT)
factor.scores(fit)
What about Partial Credit Model (PCM)? For PCM I use PCM function from
eRm package. Is there any similar function like factor.scores to
estimate ability scores using PCM model?
Best,

Multiple comparison and two-way ANOVA design

I'm working on multiple comparison design on two factor (2 3 levels)

samba_kcc RODC failes with NT_STATUS_ACCESS_DENIED
Hello Rowland,
of course it will be started by samba, I saw this output if I run "samba -i".
But I can trigger this output also by starting samba_kcc manually.

possible memory leak in ldb module while dbcheck on RODC
Hai Andrej,
Oeps, Sorry, my mistake 4.6.x needs at least 1.1.29.
But you can upgrade to 4.6.x ;-)
Check again and if that problem then still exists,
then i think you can better ask this one in the samba-technical list.
Or if Rowland knows something more about this.
One tip, wait untill tomorrow or the weekend, there wil be a new release due to the regression bug.

2 questions regarding base-n and identifing digits
Dear listers,
I have two questions:
(1)
Is there a way in R to change the base-n of the calculations. I wnat to run
some calculations either in binary (base-2) or base-4. Is there a way to
specify that in R - to chnage from the decimal?
(2)
I also want to extract the digits from a larger number and store them as a
vector.
I could do it through converting top string, parsing the string and

automatic model specification
Dear listers,
I must first say that all the suggestions and help I
got from the list so far was of great help to my work.
I approach you with another question. Is it possible
to generate an automatic specification of the formula
for lme (or other models in R)? Let me clarify. I'm
using models in a simulation run and can have variable
number of variables in the data. I would like to

Should Samba-tool RODC preload be run periodically?
Hello list,
I run “samba-tool rodc preload” for multiple users. If one of this users change his password, should I repeat the preload call? (I suppose yes, I need to rerun)
If I need to rerun samba-tool, can user login with his old password till its expire? (I suppose yes?)
Thank you.
