You don't need a loop for this, I think. Since you don't provide an
example it's hard to know how your data are set up, but look at this:

Hi
I have tried many attempts but cant get the loop right, as I am not a strong

Hi guys, my doubt is quite simple,
I´ll try to explain:
test = matrix(0, nrow = 783, ncol = 12)
for (x in 1:9){
for (y in 1:12){
### In the original script for each y its generated a vector (87x1)
### 87 times 9(x) = 783 (equals the number of rows I want to fill in the
"test" matrix
}
}

Dear Amit,
The following should get you started. What I'm doing is creating an
identifiers (g) with the "names" of the columns you want to group for and
then use a combination of apply() and tapply() to get the mean for each row
in the levels of g. In your case, you have more columns than I have in
I'm not quite sure what you want to do, but this might help:
d=data.frame(replicate(40, rnorm(20)))
d$sample=rep(c('a','b','c','d'),each=5)
lib(doBy)
summaryBy(.~sample,da=d)

Hi
I am trying to create a loop which averages replicates in my data.
The original data has many rows. and consists of 40 column zz[,2:41] plus row
headings in zz[,1]
I am trying to average each set of values (i.e. zz[1,2:3] averaged and placed
in average_value[1,2] and so on.
below is my script

I am trying to make an array c(3,8) that contains the averages of what is in
another array c(9,8). I want to average rows 1:3, 4:6, 7:9 and have a loop
replace the generic 1:24 values in my array with the average of the three
rows.
The problem I am having is that R only replaces the last value
16 matches
