Respected R helpers/ users
I am one of the new R user. I have a problem regarding to know which of the integer in each column of the following matrix is in majority. I want to know that integer e.g. in the first column 1 is in majority. Similarly in the third column 4 is in majority. So what is the suitable way to get the desired integer for each column. I am looking for some kind reply. Thanks example:
> x=matrix(c(1,1,1,2,2,2,2,3,3,3,3,4,4,4,4,4,1,2,3,3),ncol=4)
> x

     [,1] [,2] [,3] [,4]

[1,]    1    2    3    4
[2,]    1    2    4    1
[3,]    1    3    4    2
[4,]    2    3    4    3
[5,]    2    3    4    3
