[R] "mode" function

[Dejian Zhao]

 R does have a mode function, but it seems NOT to do the same thing as in 
matlab.

 > A <- matrix(c(1:3,1,3,2,3,3,2),nrow=3,byrow=F)
 > A
      [,1] [,2] [,3]
[1,]    1    1    3
[2,]    2    3    3
[3,]    3    2    2
 > A[,2]
[1] 1 3 2
 > mode(A)
[1] "numeric"
 > mode(A[,2])
[1] "numeric"

In other programs I use (such as Matlab) I can have for exampe a 3X3 matrix A, A=[1 2 3; 1 3 2; 3 3 2] and I can find the mode of the rows so that mode(A[1:3,:]) returns a 1X3 matrix [1 3 2].
