I have a data set

I want to tabulate in the following way.
1 2 3
x1 3 2 1
x2 2 3 0
x3 3 1 1
It is just like frequency distribution
See function table.
and colnames() and col()
If your data are in a matrix or data.frame called 'dat'
table(colnames(dat)[col(dat)], unlist(dat))
1 2 3
x1 3 1 1
x2 2 3 0
x3 3 1 1
