Dear R-Help Team,

I have been trying to sort (all columns of) a matrix:

> a<-matrix(a<-c(1,3,4,6,6,4,6,56,4,64,86,39,4,2),length(a),2)
> a
      [,1] [,2]
 [1,]    1    1
 [2,]    3    3
 [3,]    4    4
 [4,]    6    6
 [5,]    6    6
 [6,]    4    4
 [7,]    6    6
 [8,]   56   56
 [9,]    4    4
[10,]   64   64
[11,]   86   86
[12,]   39   39
[13,]    4    4
[14,]    2    2
>
I would like to have the matrix sorted and the output should again be *a
matrix* with nrow=length(a) and ncol=2 just like (a) but only
sorted. Whatever I try (be it sort(), order()...) I receive a vector of
length(a)*2...

Could you please help me?

Best regards,

kajan
