writing a function
Dear lists,
I'm in my process of learning of writing a function. I tried to write a simple functions of a matrix and a vector. Here are the codes:
mm<-function(m,n){ #matrix function
w<-matrix(nrow=m, ncol=n)
for(i in 1:m){
for(j in 1:n){
w[i,j]=i+j
}
}
return(w[i,j])
}
v<-function(n){ #function of a vector
y=vector(length=n)

matrix loop
Dear list,
I'm trying to make a loop of a (5x10) matrix and below are my codes. Could anybody help me figure out why my loop is not working. Thanks in advance!!
m<-1:5
n<-1:10
for(i in 1:length(m))
{ for(j in 1:length(n))
{
y[i,j]=sum(i,j)
y<-as.matrix(y[i,j])
}
}

reverse vector elements
Dear lists,
I want to write a function of a vector and reverse the order of its elements. Here is my code:
revector<-function(n){
y=vector(length=n)
for(i in n:1){
y[i]=i
}
return(y)
}
i want my output to be like this:
y

Any suggestion?? Thanks!!

p-value
Dear R User,
say I have this sample of data ( attach with). What i'm going to do is to test whether this data is uniformly distributed or not by finding the p-value. I've tried using the punif command but it gave me the value of 1 of all the data. Any suggestion on R command to find the p-value??Thanks in advance!!

extracting elements by using logical values
dear lists,
My question is quite simple but i'm a new user in R and it's seem tough to me. How am i going to recall back my values??ok..it could be easy if i ilustrate my problem with the simple example. say that,
x
[1] 1 2
y
[1] 2 3
and my logical output from my function are (Below is my function):

stripchart
hi,
I want to plot a dotplot graph but unfortunately R does not have it any more. It suggest to use either the stripchart or the dotchart and i prefer to play around with the stripchart graph. Sadly, the result is not like i want where I'm actually wants the plots/points were scattered around the x-axis. Plus, from the results shows that and the x-axis gave a very large scale, i.e

finding the suitable distribution
Dear R-users,
Attach with is my data..what i want to do is finding a suitable distribution for my data..I want to run a few test like the poisson and the exponential distribution. Please help me on how to find the p-value for poisson as well as the exponential distribution without knowing the parameter. Is it possible?? Thanks in advance.

dovecot replication - new and cur folders on mx1 and mx2
Hello,
I have a question in regards to specific dovecot replication behaviour
and I'm just wondering if this is actually an expected/normal behaviour,
or just a version issue.
I'm using dovecot 2.3.16 which is packed by default with latest Ubuntu
22.04.1 LTS server release. I setup dovecot replication pair (mx1 - mx2)
which is working ok. MX1 has priority 10, MX2 has priority 20. I

dovecot replication - new and cur folders on mx1 and mx2
I can confirm this in a slightly different setting, but still using two-way sync between two dovecots. On e is 2.3.19.1 running on macOS Monterey, the other is 2.3.20 running in an alpine container on Ubuntu.

dovecot replication - new and cur folders on mx1 and mx2
It might have a noticeable effect on clients.
I encountered (probably triggered by this in some way?) that I was unable to het the 'read' bit set in macOS Mail.app. Maybe (as I am doing HA with round robin) the Mail.app client got to one dovecot repository on one tcp connection and then on the other.
Is there a reason why syncing tis move from new to cur is a bad idea?

coalesce columns within a data frame
Dear all,
I searched the mail archives and the R site and found no guidance
(tried "merge", "cbind" and terms like "coalesce" with no success).
There surely is a way to coalesce (like in SQL) columns in a
dataframe, right? For example, I would like to go from a dataframe
with two columns to one with only one as follows:
From
Name.x Name.y
nx1 ny1
nx2 NA

DNS DoS attack
Looks like one of my name servers (CentOS 5) gets a lot of malicious
queries. The cpu load is constantly about 3 %. I put on stricter limits
on who is allowed recursive queries, but this does not affect the CPU
load. I also updated bind.
I temporarily turned on querylog (command: rndc querylog), and noticed
that I get over 200 queries like this per second:

Novice question
Hello.
I am new R user, so this question is probably quite stupid, but for
the life of me I cannot figure out how to get predications using
multivariate linear regression analysis. Single variable predictions
work fine. I am trying the following:
