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
