[R] Handling of arrays

[laptopcss at gmx.de]

Dear R-Experts,

I just imported a workspace from Matlab. I know that I can get the names of the imported variables with names(). It works. The variable "ca" consists of several elements. I want to get the names of the elements to handle my output better. But names(ca) doesn't work. Why? I did the following commands:

> class(ca)
[1] "array"
> mode(ca)
[1] "list"
> dim(ca)
[1] 66  1  1
> length(ca)
[1] 66

How can I now get the names which are stored in ca? When I use the command "ca[18]" I receive the content which stands there but not the name collables which I wanted to extract. 

Any ideas?

Thanks, Corinna
