Did you try my function? I don't see how it doesn't fit the need of this
reexplanation.
For this set, x would end up equal to c(2,2,1), indicating that array 1
appears twice in the set and array 2 appears twice in the set. So, array 1
and array 2 appear maximally in the set. So, look at a[[1]] or a[[2]] and
that is your answer.

Thanks for the effort but still we are far from the desired result. May be
this example will help you to understand the situation. Example
a1=c(1:12); a1=array(a1,dim=c(3,4)); a2=c(1:12); a2=array(a2,dim=c(3,4));
a3=c(1:16)
a3=array(a3,dim=c(4,4));
a=list(a1,a2,a3);
a
[[1]]
[,1] [,2] [,3] [,4]
[1,] 1 4 7 10
[2,] 2 5 8 11
[3,] 3 6 9 12
[[2]]

[1,] 1 5 9 13
[2,] 2 6 10 14
[3,] 3 7 11 15
[4,] 4 8 12 16
Here [[1]] and [[2]] are same out of three (internal values wise). The
whole array [[1]] or [[2]] is in majority. So i want to get the whole
array or component of list which is in majority. The result should be like
this
[,1] [,2] [,3] [,4]
[1,] 1 4 7 10
[2,] 2 5 8 11
[3,] 3 6 9 12
Hope it is much more clear as before.

That is indeed different from what I thought the first time.
x <- sapply(1:length(l), function(x) {
sum(sapply(l, function(y) {
if ( nrow(l[[x]]) != nrow(y) | ncol(l[[x]]) != ncol(y) ) FALSE
else sum(y != l[[x]]) == 0
}))
} )
names(x) <- names(l)
Then, x has the same names as l, and x[i] is the number of matches that
l[[i]] has...so you want the index or indices of max(x).

May be i could not explain properly. Actually there are components of
list i.e. [[1]] to [[500]]. Each component containing r-rows (may be
different for each [[ k ]] and c-columns same for all). I have to
compare all the [[ k ]] components of that list and found the one
appearing maximum no of times. e.g. from three components [[1]] to
[[3]] given below. The most repeated is
[,1] [,2] [,3] [,4] [,5]

If want you want is the summary from all of them, then 'rbind' the
data together into one matrix and analyze it:
totalMat <- do.call(rbind, listOfMatrices)

Dear R community
I have stored the results of arrays in a list consist of J-components
(say 200 components). Each component containing same no of columns but
may be different no of rows. e.g
[[1]]
[,1] [,2] [,3] [,4] [,5]
[1,] 4 0 0 0 0
[2,] 4 3 4 0 0
[3,] 4 3 4 0 0
[4,] 4 3 0 0 0
[[2]]
[,1] [,2] [,3] [,4] [,5]
[1,] 4 0 0 0 0
[2,] 4 3 4 0 0
[3,] 4 3 4 0 0
[4,] 4 3 0 0 0
[[3]]
[,1] [,2] [,3] [,4] [,5]
[1,] 4 0 0 0 0
[2,] 4 4 1 0 0
[3,] 4 4 1 0 0
[4,] 4 4 0 0 0
[5,] 4 4 0 0 0
For 200 components i want to make a frequency table. How can i make a
frequency table of these components or the most repeated component out
of all? Any help in this regard will be appreciated.
