Hi everyone,
I have dataset which I take random samples of it 5 times. each time I get
the mean for rows for each sample.
at the end I need to calculate the Average of all means for each sample and
each row. to clear it up I give an example:
say this is my dataset.
X8 X9X10X12 X13 X14 X15 X16X17X18X19 X20 X21 X22
s1 0 1 0 0 0 1 0 0 0 0 0 0 0 0
s2 0 0 0 0 1 0 0 0 0 0 0 0 1 0
s3 0 1 0 0 0 0 0 0 0 0 0 0 1 0
s4 1 0 0 0 1 0 0 0 0 1 0 0 0 0
I get a random sample and mean of row for that sample(5 times , but I just
put 2 of them here to give you an idea)
X12 X9 X10
s1 0 1 0
s2 0 0 0
s3 0 1 0
s4 0 0 0
s1 s2 s3 s4
0.3333333 0.0000000 0.3333333 0.0000000
X10 X18 X8
s1 0 0 0
s2 0 0 0
s3 0 0 0
s4 0 1 1
s1 s2 s3 s4
0.0000000 0.0000000 0.0000000 0.6666667
This is the code I used:
for(i in 1:5)
{
temp<-sample(A3,3, replace=F)
Avg=rowMeans(temp)
show(temp)
show(Avg)
}
Now, the problem is how can I save the result for each row(s1,s2,s3,s4) so
that I can get the grand average from 5 runs?I thought about using a vector
in the "for" loop but it's no good, it over right so basically I only get
the means for last sample. any idea how to do it?
Thanks a lot
