How Is Administrator Treated?
I have a couple of Samba 2.2 servers, in different locations, configured as
NT Domain Controllers, but I'm experiencing some problems with logging on
to the domains as Administrator in order to perform some administration
tasks, such as configuring antivirus software on workstations. I won't go
into the details here; I think the basic problem is my lack of
understanding of how the

Mapping of Unix groups to Samba user permissions
I ran into a problem today which surprised me, and after two hours of
reading and testing I am more confused than ever, so I feel the need
for a sanity check. It would be good to have a clear and authoritative
article about this somewhere; I thought it would be in either "Using
Samba" or in the HOWTO, but I don't see it there.
I am using Samba in several installations in homes and

find closest value in a vector based on another vector values
Dear All,
would you please provide your thoughts on the following:
let us say I have:
a <-c(1,5,8,15,32,69)
b <-c(8.5,33)
and I would like to extract from "a" the two values that are closest to the values in "b", where the length of this vectors may change but b will allways be shorter than "a". So at the end based on this example I should have the result

Hlink node data for 2282618 already has path=...
So, like a lot of people, I am using --link-dest to do backups. My
backup target is ext4 so with a hard link limit of 64K. I do end up
with trying to create too many links at some point though and get the
following sequence of events:

Help on numerical object and ifelse function
Dear All,
this is probably an easy one but I can not get a handle on it:
x <-c(1,2,3,4,5)
y <-c(6,7,8,9,10)
z <-15
w <-ifelse(z>14,x,y)
this will give me a value of 1 for w. What I would like to get is the whole string of x, so that w would become a numeric object of 5 characters exactly the same as x.
Apreciate the help,
Sincerely,
Andras

Help on finding specific columns in matrix
Dear All,
I have a matrix with 33 columns and 5000 rows. I would like to find 2 specific columns in the set: the one that holds the highest values and the one that holds the lowest values. In this case the column's mean would be apropriate to use to try to find those specific columns because each columns mean is different and they all change together based on the same "change of rate

Help on converting a Sweave document to PDF
Dear All,
I am working with a Sweave document to be converted into PDF using Rstudio. It seems to me that my R code will also show up after conversion, which I would like not to happen. Is there a way to specify a command that I could place on the beggining and at the end of the R code that would allow R to recognize the area where my R code is and would ignor it when the data is converted?

"Re-creating" distributions
Dear All,
I often have to work with certain models in which I try to "reproduce" a distribution the best I can with very little known information avaible. Is there a package or function in R that could best reproduce a probability distribution using only the mean, median and SD values availble without knowing the actual distribution type to begin with and/or the covariance matrix (for

simplifying code
Dear All,
I was wondering if you could help me with the following:
I have the code:
tin <-0.5
tau <-24
output0 <-10
TIMELOW <-tin
TIMEHIGH <-1*tau
TIME1 <-c(seq(TIMELOW,TIMEHIGH, by = sign(TIMEHIGH-TIMELOW)*(tau-tin)/3))
then I would like to calculate:

cp2 <-output0*exp(-0.3*TIME1[2])
cp3 <-output0*exp(-0.3*TIME1[3])

Apply a function to columns of a matrix
Dear All,
as a follow up to my previous e-mail (I think I am getting closer...):
I am trying to apply the trapezoidal functions to a matric column by column. I have the following code:
a <-matrix(c(1:100),ncol=10)
b <-matrix(c(2,4,6,8,10,12,14,16,18,20))
apply(a,2,function(b,a) sum(diff(b)*(a[-1]+a[-length(a)]))/2)
for some reason i get an error message:

remove specific number of rows from a matrix
Dear All,
sorry, got stuck again on the following: let us say we have:
a <-c(1:5)
b <-c(6:10)
d <-cbind(a,b)
from d I would like to remove total number of rows based on the length of f. So if:
f <-c(1)
my result is working great with the following solution:
d[-length(f),]
so I get: a b
[1,] 2 7
[2,] 3 8
[3,] 4 9
[4,] 5 10 but if I do: f <-c(1,2) then I get:

how to skip part of the code
Dear All,
another quick question, this one is on skipping part of my code, so let us say:
a <-5
b <-2
e <-0
d <-a+b
f <-a-b
what I would like to do is to have R NOT to calculate the value for d in case the value of e equals to zero (essentially skip that "chunk"), but instead move on to calculate te value for f. In the code I am working with the value of e changes,

screen if a value is within range
Dear all,
could you please give me some pointers on how I could make R screen for a value if it falls within a certain range?
I looked at the subset function, but is not doing it, perhaps because I only have 1 value to screen?
aptreciate the input
ex:
a <-16.5
I would like to screen to see if a is within the range of 15 to 20, (which it is:-)), and I would like the code to return a value
