Hi,
Suppose
a=matrix(1:9,3,3)
> a
[,1] [,2] [,3]
[1,] 1 4 7
[2,] 2 5 8
[3,] 3 6 9
Now,
> class(a[1:2,])
[1] "matrix"
> class(a[1:3,])
[1] "matrix"
> class(a[,1:2])
[1] "matrix"
> class(a[,1:3])
[1] "matrix"
But,
> class(a[1,])
[1] "integer"
> class(a[,1])
[1] "integer"
Can in a general way get class(a[1,]) or class(a[,1]) to be "matrix" only?
