While loop working with TRUE/FALSE?
Hi R users,
is there any possibilty that a while loop is working like that:
z <- c(0,1,2,3,4,5,6,7,8,9)
r <- 7
while(w == T) {
for ( i in 1:10 ){
w <- r == z[i]
print(w)
}
}
The loop should stop if w == TRUE
best regards

Substitute problem
hello R users,
I didn't find a solution for a special problem.
I have two dataframes.
dataframe1:

Make one vector from matrix comparison
Hello R-users,
I have a little problem.
I compare each row of a matrix with each row of another matrix.
testmat1 <- matrix(c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16), nrow=4)
testmat2 <- matrix(c(1,2,3,5,5,6,7,8,9,10,11,12,13,14,15,16), nrow=4)
Both matrix differs in the last row.
Now I create a loop:
for (i in (1:4)){
for (j in (1:4)){
b <- (c(setequal(testmat1[j,],testmat2[i,])))

points() colored by value
Hi R users,
I want to colored points by their value
for example:
x <- c(1,2,3,4)
y <- c(1,2,3,4)
z <- c(2,3,4,9)
y and x are coordinates
z is the value of the coordinates
points(x,y,col= rainbow(z))
something like that
But haven't found any solution at the moment.
Thanks.

How to save row values from a matrix into one vector?
Dear R users,
I guess, I have a quit simple problem, but I'm not getting the solution.
I create a matrix like this:
test <- matrix(seq(1,3,1),ncol=5,nrow=3)
then I want to create one vector, consisting of every row of the matrix.
My first idea was to do this with a for loop.
op <- vector()
for (o in 1:3){
op[o] <- as.vector(test.id[o,])
}
The results should be like this:
[1]

add string to a list
hello R users,
I didn't find a solution for a simple problem I think.
I read 224 lines from a file
input <- readLines(con,n=224)
and now I create a string x <- "\004" which should be line 225 of input.
So I have input and x and want to add x to input, so that it looks like
this:
[1] "string"
[2] "string"
.
.
.
[224] "string"
[225]

substring and paste character with a for loop
Hello R users,
I have a little problem with a for loop.
Below there is an simple example of my problem.
I want to delet the commas in the character string. Fore this reason I
create a for loop to unpick the string and rebuild him without the commas.
The problem is, that "paste" does not work in the loop as I expected.
text <- "aaa,bbb,ccc,ddd"

R process slow down after a amount of time
Hi R users,
I have mentioned that R is getting slower if a process with a loop runs for
a while. Is that normal?
Let's say, I have a code which produce an output file after one loop run.
Now after 10, 15 or 20 loop runs the time between the created files is
stongly increasing.
Is there maybe any data which fill some memory?

Searching a relativ maximum of a matrix
Hello R users,
is there a possibility to get the relativ maximum of a matrix?
To get the absolut maximum I use max(matrix)
For example:
The absolut maximum of this matrix is 6[3,6], but the relativ maximum is
6[3,6] and 4[7,6], because both values are the highest value in comparison
to their eight neighbours values.
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8]
[1,] 1 1 2 2 2

Hi,
I posted the message below last week, but no answers, so I'm giving it

drive to standby after idle timeout?
I'd like to to put the hard drives in standby mode during periods of
no activity. I'm just running a file server plus a couple small
things on a Qube 3 from home, although the web stuff will increase
it's still minimal.
On my NetBSD systems I can use atactl to do this via:
mount -u -o async,noatime,nodevmtime /
