Dear experts,
I have a 10x2 matrix T containing random integers. I would like to delete
pairs (rows) iteratively, which contain the most frequent element either in the
first or second column:
T - matrix(trunc(runif(20)*10), nrow=10, ncol=2)
G - matrix(0, nrow=6, ncol=2)
for (i in

hello,
first I create a list:
l - list(1-c(1,2,3))
then I run the following cycle, it takes over a minute

Are there any packages and documents on how to use more advanced and
fast data structures like linked-lists, hash-tables or trees for
example?
Thank you,

consider each row as
one data point, and not all elements in the matrix separately:
as.data.frame(table(M))
M Freq
1 12
2 22
3 31
4 41
Any help greatly appreciated!

the vectors
(containers) in the matrix are usually of different length.
Any help greatly appreciated,
