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).

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]
[1,] 4 0 0 0 0

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.
