Hi R users,
I have a matrix of data similar to:
I would like to know to which decile each number belongs compared to the
numbers in its column.
Say y[1,1] is the third decile among y[1:11,1] and y[2,1] is in the second
I would like get a matrix that would return their ranks in decile, i.e.,
y[1,1] -> 3
y[2,1] -> 2
Your help is much appreciated!
