I'm quite new to R, so excuse me if this problem has a simple solution.
I'm working with an array, lets say
i <- array(c(1:3,3:1), dim=c(3,2))
Then I want to give the rows and the columns names:
The result is given below:
a 1 3
b 2 2
c 3 1
Here comes my problem. When I'm taking a submatrix
the result should be (for me) an array of one line, and two colums. Here's
When I want to access the rownames of j, it returns NULL. I want it to be
On the other side, if I take a submatrix 2x2, there is no problem.
In my problem, rownames(j) must return the name of the extracted row. So I
don't understand why a 1x2 array is not a normal array.
Could someone help me with this?
Thanx in advance,
